Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

First generation tablet(2010) was Sylvania with Via cpu at 300 mhz. $99 with coupon sold at $75.

Now CVS has Craig tablet(2011) at 700 mhz ARM11 cpu running 256 mB Android 2.1 or 2.2. MiniUSB connector provided. MicroSD flash card for 32 gB can be inserted. Cheaper than $75 if you use both coupon and gift card($25). Employee of cvs can buy at $60. Resistive 7" touch screen is 800x480 resolution. 1080x400 maybe the future model with 1.3 ghz Arm A8 cpu(2012).

Android 3.0($300-400 or $28/month) is what everyone is waiting for? But then, does any one want Android 3.1 with USB 2.0? Android will never be the perfected software to do the job you want? Smartphones are always missing some functions that tablets needed. Its chasing rainbow all the time.

Today, netboooks are changing video platform to hdmi, which made USB bus now key to new architecture for all peripherals. Platforms without peripherals of USB devices are cripples at best. Those still using vga are slower than hdmi and need huge drams for internet cloud computing. Google has yet to wake up to this new reality.

Free WiFi hotspot is everywhere, but some instructions are needed to get on it easily. Not to be confused by encrypted hotspots. 3/4g modem can be using USB adaptors, but its expensive.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

The reason for WiFi tablets is to access data centers or portals to do cloud computing, not limited to your home.

Thin client concept is perfectly acceptable.

Wifi free hotspot has to have some security and traffic control to have locked paths. Security can be just a list of users on the hotspot(and their assigned ip address on time tables), as long as their identity is known on the router.

As long as tablets will have data source stabilized on standards and availability, tablets with a stable browser will never be obsoleted in decades or centuries. Mobile data(online banking) can be text or voice for speed of delivery.

Once WiFi is on GPS satellites, tablets can be clipped on automobiles for trip, entertainment, etc.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Tablet efficiency came without keyboard and mouse. some has 4 way accelerometer to detect sudden forces to activate the tablet. Touch screen control has yet not multi finger input on the cheapest tablets. Some of these extra controls such as gyroscopic, may never be needed for table top use, or only exclusive for automobile use in gps mapping without GPS communication traffic.

Tablets thus are more capable than desktops. It is less cumbersome than laptops. And it has more features than smartphones.

It will become a perfect display for enterprise system(business) on the run.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

The earlier tablets that used Android 2.1 or 2.2 really are not quite good enough. No flash player means many websites can not be displayed correctly by google browser that insists on html5 etc. Adobe autoupdates all active-x directory of many webpages to make touch or mouse action activated on each webpage(no error on page mistakes). Adobe is not just mpeg4/h.264 but also all the active-x directory for touch and mouse actions which needs autoudpdated as soon as browsers change to new format.

Then, webtablet is really crippled for cloud computing without Adobe flash player. Some tablets can not do Market(apps store) downloads. If you think google can be versatile enough to do cloud computing, you may have to wait a few more years for further development of their technology and generally a policy change to view all media on the internet with all the protocols. Once Google tried to set their own standards and failed to observe telephone company protocols and cableTV protocols, Google will be missing out a lot of data media usability.

This means the really cheap tablets of Android standards are not good investments. ARM cpus without consistent instruction set and usable branch predictions(Thumb or Thumb-2) may have problems with Linux kernels itself(bugs galore inevitable). Windows8 will have three kernels for Cortex A, R and M(option on cpu brand), depending on which one is being used.

When we process movies of Mpeg4/h.264 instead of mpeg2, we have 70% savings in data length. Then if we run thumbnails of 900% resolution reduction using FPU, we save even more time to process the reduced pixel codes. These feature are now designed into cpu architectures to view movies or any webpages(cloud computing).

Footnote:
Android market needs gears to use browser display, which is why market gets locked out of some Android versions by Linux kernel versions. Gears today can be put into realtime packets to run gears(javascripts) in the webpage(Twitter).

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Common problems using ARM cpu old or new, is the cpu architecture, which often has different embedded features. The branch prediction(Thumb and Thumb-2) for 32 bit processing of 4 8bit long instructions are different from Intel 32 bit cpus. Then there is the memory boundary of IBMPC, which is 1 mB. ARM cpu has no boundary(offsets are different) except the size of dynamic memory installed or nand flash memory size installed. ARM computer architecture is similar to mainframe computers, just buses, cpu and memory. USB bus is used to run peripherals.

Once ARM cpu is selected, designed and installed. Its a different platform using different instruction set. You can use pixel video scanning of hdmi connector. Touch screen and voice commands input to the cpu.  Then you compile for applications within your memory limitation, and install all the USB device drivers.

So, the tablets are not the same architecture as IBMPC. Its cheaper and simpler yet more powerful when buses are serial data only(from L2 cache to USB). That means serial data has to be run faster than 5 ghz to beat all IBMPC speeds. Cpu parallel data processing speed can be slower by a factor of ten(1 ghz to run 10 ghz serial data from internet). The logic of using WiFi 10000 mbps(10 channels of 1 ghz data) someday is not far fetched speedy concept on 1 ghz cpu.

Ah, got you. Design of computers has to start at the telephone company? Then design of the internet has to be ipTV and its radio carrier frequencies for data channels, then IF frequencies for discrimination of data. then you can still add multiplexers for more data channels.

Computer companies had to adapt to these consumer electronics standards(protocols) to function better and within modern data traffic control schemes.

Footnote:
Linux kernels used i386(no 32 bit branch prediction as 8 bit Risc cpu) and compile with GCC 3.x, so mulitcores will run in symmetrical processing, very slow(4 cores run 2x speed of a single core). Multicore ARM should run multitasks on priority(IRQ). It will take a few years to iron out shared library from symmetrical processing.

Android runs on javascripts(graphics) supported by C compiled binary codes. C is faster, And browser is the operating system. No peripheral drivers until USB 2.0 is in v3.0(honetcomb). WiFi should keep it running a little faster than cellphones.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

When a computer is choked on input and output data transfer speed, the computer is slow and high speed cpu is useless. Data transfer speed on any bus is important design criteria to consider when you build any computer.

Originally, data I/O is the keyboard and mouse and monitor display, using only the desktop(and your brain, both slow) on the computer. The cpu speed is the only thing that counts. Today, data I/O from the internet involves many servers, and telephone companies and their infrastructure. The speed of data transfer is more critical, and denial of internet service can not be tolerated. 350 mbps is not the limit of internet data transfer rate. CPU of 350 mhz is over ten years old. ARRS announced 4.53 gbps speed using 128 data channels(based on rumors of a 128 channel tablet being built in China) for cableTV customers. But is it sufficient and good for how long, since edgeQam transceivers are 500 channels of data transfer simultaneously for many years already(since year 2005).

So. Intel and Wintel is outdated technology.  Arm embedded cpus are being used for analog digital mixed signal of data I/O. Computer bus speed has to be designed faster, and use of reduced pixels(thumbnails) transmission is part of the hardware and software design for data I/O speed. The cost of a tablet to have higher bus speeds is hardly costly, it does not take a rocket scientist to know the future and direction of communications technology.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

The choice today for operating system of tablets is limited to high end iOs of Apple and low end Android 2.1/2.2 with USB(Android 3.1 will be ready soon). Microsoft is sort of ready with WinCE7 or EC7 with IE7/8, until Win8 is ready 2012.

So, we have very little to look forward to, as far as investment on a new tablet is concerned.

The problem is further confused by ARM cortex A, R, and M versions of cpus. Microsoft is still supporting symmetric multiprocessing multitasking which is slow. They should change to packet switching multitasking by hypervisor to reassign priority of tasks on free cpu cores available. Fell over if busy usage of cpu cores.

So, the discussions on tablets, inevitably resolve to the operating system for ARM cpu multicores. Too early for a final choice to be sure. In the mean time, they all have to chase the rainbows of embedded features designed into apple iPads(iOs).

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

There are reports of tablets with Andriod 2.2 quite usable, with Adobe flash for all the webpages and USB 2.0 for many USB devices including printer, pdf files are formatted to 800x480. The instant on is real nice, better than netbooks. Live GPS is great if you are traveling.

Tablet manufacturers are making Androids more usable by small changes.

Future changes desired maybe voice command for text input. USB computer, cpu and virtual terabyte(video braaille colored dot data compression) memory add on for paperless applications(by data storage methods thru monitor display).

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Once the tablets are sold at a discount at the drug stores; online distributors became shy at buying any large quantities of any brand, no price protection. Consumer electronics firms are now making tablets, competing with Wintel. Intel has 60 million motherboard production capacity per year for Dell. Computer brands lost all their good will, even HP. Acer bought brand good will not market share, Asus did not keep up their new product flow at the online stores. Only old fashioned way of occupying the buyers office can now get a market share.

Thus tablets may eventually be marketed at the grocery stores, for quicker turn over.

Tablets(Android or ebooks) are made better(touch screen technology problems), once larger quantities are produced; Quality control will be tighter. Early Androids may have design faults or flaws.

First generation cloud computing tablets are designed with 2 gB memory, which has to use RTOS webpages and reduced pixel data transfer(Adobe flash player with mpeg4/h.264 zoom feature). This made Wintel obsoleted by too much memory and slow data channel data rate. You waste a lot of money doing the older ways of computing.

Netbook was saved by $3 XP over the Linux bugginess galore. But now Windows7(bloatedness) killed the netbook initiative(small dram memory design with large hdd for virtual webpage history). Tablet design(instant on touch screen) continued on netbook initiatives with larger microSD flash card instead of hdd for longer battery life.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Computex show in Taipei had many new tablets; mostly netbook concept with detachable keyboards. Which makes tablets less mobile. Tablets should be small, light, and tough.

However, there are reports of possibly shoulder pains from holding tablets(1 lb) up too long. So, eventual voice commands and table stand for vertical viewing will come in the tablet package. These are usage problems not anticipated.

Recent advanced webpage RTOS made voice commands easier with limited number of words that can be different from too many voice commands causing confusion. We might get lucky with choice of words for voice commands similar to GPS navigator voice commands.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Desktops are dead in the water. When you turn on the computer, desktop shows you all the applications. But each day the applications need your own inputs. If you are not creative that day, your computer had no more data recorded than yesterday.

Tablets and smartphones, booted with connection to the internet. You can have 12 or 20 windows, each with an application that you will get updated, things happened while you were asleep. This is cloud computing with a browser.

Desktop thus got replaced by browser many years ago. The difference today is the connection to the internet via tasks, and the speed of the data transfer. The webpages are the tasks in summary. One webpage is one application software.

Tablets and smartphones can be connected to the internet 24/7, Each window can show you changes by the seconds.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Tablets are now sold in 3g version or wiFi version. The difference being you boot on your cellphone account to a browser like prex0.4 or you boot into ethernet(or USB) Wlan and dhcp shared access point WiFi radio tuned hotspot(s) to connect.

Not everyone has free wifi hotspot at home. But if you travel, many locations have free wifi.

The way it is now, cellphone has to be attached to WiFi tablets(USB) to get the sim card for both devices.

Tablets can not replace cellphone, but cellphone can do all tablets ever can do, unless tablets can have a handset(sip or skype) to the ear for privacy or cellphone by usb connection.

Tablet market will soon sort out the features needed.

Because Android is bloated Linux distro, it can be stripped down to Austrumi or Puppy or SliTaz or tinycore to run either cellphone or Wifi connections for internet, with Firefox too. If knopper sees this post, please make a version of LiveMicroSD for tablets to dual boot with Android in 2 or 4 gB fixed memory(hack and redirect grub to MicroSD).

There is no question, tablet form factor is here to stay. consumer electronics will support this computer design and architecture combining Radio, TV and telephone(mpeg4/h.264 zoom feature) to work on internet media(cloud computing) around the world.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Tablets' hardware are not uniform, so operating system supplied by manufacturers are different, especially if the ARM cpu is different. ARM cpu is designed by drivers of embedded features on the RISC(+-), changing instruction sets by the branch prediction codes. So, eventually, we have to expect a shake out(branch prediction codes) of the many ARM cpus on the market. CISC is (+-x/) and ascii codes for console, very simple.

The cheap price points of consumer electronics tablets eventually will be sorted out by application features of human engineering and performing tasks.

Minimum tablet feature is internet connection. But GPS and voice will be a major requirement to be on the tablet.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

ARM cpu uses only 30,000 transistors* per core(battery last longer). Needs radio antenna for bus internally to speed up data transfer and break the 2 ghz frequency barrier. Uses only 256 mB of execution memory in nand. 2-4 gB software storage to run on the internet. Need to insert additional 32 gB of microSD to make it more powerful with more apps.

The design uses fast Wifi connection to make slow cpu appear faster. Avoided many video protocols go directly to TV monitor. The tablets are thin and light to carry. But resistance touch pad need more touch pressure.

This circuit design with USB and hdmi, has no equal for now for 8 hour battery life, and CVS had pretty much sold out early versions of Sylvania and Craig tablets(800 mhz). This Xmas, the new models will be 1.3 ghz.

Next year will either be ARM multicores(currently ARM+DSP for SXGA) or 2 ghz radio serial FSB.

Footnote:
Nand has 256 mB of non-volatile SRAM and the rest high data compression 2-3 gate nand memory. This can be used cleverly to avoid DDR circuit. overflow of 256 mB memory will be store in nand automatically immediately.

Footnote 2:
*Intel atom cpu is 47 million transistors; i7 is 865 million transistors.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

ARM begun with MosTech 6502 which was used among others also in AppleII computer. It has many advantages but was redesigned for 32 bit computations. It uses thumb and thumb2 branch prediction in many stages, but not as many stages as Via or Intel Pentium. So, it could be run 1/3 faster.

The fact that it uses less transistors also uses less power. Battery life doubled.

Cellphones can be made much cheaper with such architecture. And the fact that production quantity is very high, the cost had been trimmed down long ago.

What ARM has to avoid is bloated multimedia codes. It worked best with reduced pixels per video frame. So, for hdmi video, its ideal. Movies and TV can be displayed with all the video content and stereo sound. No much graphics or audio missing.

At 1/4th of Intel circuit cost, and can perform good enough is the way to eliminate digital divide for third world countries. And as long as the display can satisfy enterprise text webpages(online banking), who cares if it has not too much graphics to feed the eyes(get the work done or wait for graphics experience to please the eyes).

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Bought a Sylvania netbook on ebay, with Via WM8505 or ARM926 cpu, 1 ghz. with 2 gB of flash memory. divided into 256 mB and 1.69 gB of nor. Has three USB sockets, and a SD flash card plug-in. Came with WinCE(c6g), a very minimal windows operating system. WiFi is included.

Battery is similar to dvd portable player type. Can do plenty of hours(2) until more software is added to save electricity such as cpu frequency stepping, LCD dimmer while inactive for 1 minute.

The speed of the operating system is adequate, otherwise behaves like a small laptop. Its a smartphone alright with a larger screen. Saw new one at CVS for $99.

This kind of design is for the third world to get rid of digital divide. Once you get on the internet, lie with text webpages for speed and efficiency to get task done in a hurry.

These netbooks are pretty much tablets with keyboard and mouse. Price is very attractive to say the least. Why bother with Linux bloatedness, stay with WinCE, 128 mB of codes. Maybe flashed for Android 2.1, if you are game.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

CVS profit margin is 40%, their own employees can buy at $60. Watch for CVS discount to $75 frequently.

So, the cost of DVD parts used in tablets borrowed cellphone electronic circuits. The technology is combining all the consumer electronics and mass production advantages.

What most of us don't realize is that tablets are great for experience of watching movies and TV or listening to music(add center channel amplified on headphone socket, slim folded without reflection 1/4 wave length 20-30hz boom pipes $100).

Footnote:
WinCE has WiFi configuration utility, and gets all the Wifi signals but does not tell you which one is unsecured and thus free hotspot. Most of the wifi signals are encrypted, and is only for the paid owner to use the internet. Today Wifi drivers and utility has to find free hotspots without testing each signal source to find out they need encryption to connect.

So, while wifi netbook is wonderful, software for WiFi configuration still has to be reprogrammed for productivity and efficiency. Not to use free hotspot, and only connect to your home Router is a pity.

Found a strong signal spot just outside the Framingham Library door, made this Sylvania netbook worth while. But WinCE lacked a signal strength meter before connection. It gets a strong signal but not selected source, which gives you false confidence when you move your netbook around for a strong signal to connect.

WiFi connection to website some times can lock up the use of your netbook. You have to move out of the WiFi signal to disconnect the website to recover from non-responsive problem. Or use ctrl-alt-delete to end the task.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Surprisingly obvious is the capability of Sylvania netbooks to do ethernet and USB dialup modem on Pots. Because WiFi is either router gateway at home or public unsecured hotspots available free. Unless you are in countries with nationwide hotspots, you may have no free hotspots available at times, even in the USA.

So, at home even, you may use USB dialup modem, cheaper than ethernet solution to internet(CableTV).

Otherwise you become slave to the town library. If they are closed, you have to find a spot outside of the library that may have a string signal. Are metal hand rails near the library, antenna to be used as WiFi relay to the internet?

Footnote:
WinCe network shows serial port configuration and tcp/ip address for ISP cinnection, but it lacks a dialer for USB dialup modem, Maybe it still needs a modem driver to connect to ISP network on POTS telephone line.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Netbooks or tablets, use email on the portals, which can collect all your email accounts and run all your email in one place.

Download apps into my computer directory at 240 kB/s from sylvania website. Use file manager or windows explorer to drag and drop data storage on the net(special account email with attached file) or on your main computer(terabyte hdd). Index apps(file names) for operating system of each netbook or tablet. If you only use movies or music files, no indexing is needed. Beware of documents beyond pdf files, netbooks and tablets are not suitable for different protocol. Stick to webpages only, and Google translation.

Even though there is only one removable sd card slot, the data storage is infinite if a library of sd cards and content of files are listed to be used later.

Eventually, people will make netbooks and tablets operating system more defined on the net with WiFi to go thru filter or conversion web servers for different document formats(pdf to html text).

Netbooks and tablets will make one standard from data compression method(mpeg4/h.264), then all other formats go thru conversion public servers such as language conversion or document format conversion servers, instead of forcing client computers to have bloated applications. Sylvania netbook IE6 with adobe flash lite 3.1, browser can not play youtube and internet radio stations, yet(no mjpeg+MP3 protocol and active-x directory of IE8).

Footnote:
Buying from China(koalago) still not easy, they use alibaba.com for email, and western union for payment. They should use email to their factory, for individual to pay by Paypal and get delivery confirmation. They could use Ebay but it cost more. Wholesale price from online dealer is $81-101, delivery 90 units/week(very small factory).

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

USB design faults showed up on the Sylvania netbook very quickly. 3 USB sockets had to deliver 5 volts at 500 ma current each. If you plug in two items, the 1800 ma 8.4 volt battery depletes rather quickly. If the charging circuit works, it takes 12 hours to recharge. But Sylvania semiconductor parts and electrolytic capacitors are not of very good quality. So, I bought it used for $30, and the life of the netbook seemed to fade away as the battery can not be recharged.

Unless some improvements are done on winCE and USB current drain is limited by time(current turned off for safe removal), all the sold units will be returned. Asus EEEpc had to do frequency stepping to save its market by cooling their cpu. But digital gadgets are not as experienced to solve hardware problems.

Unless the design goes thru a quick change, these products will not last in the market even upto this Xmas.

As we use these new toys, we are discovering design faults.

First, warning user not to use USB to drain the battery. Slow charger requires charging battery with adaptor during use if you have AC power. Embedded devices using ARM cpu and nand memory can not use too many apps on desktop(file switching dependency library size). Had to use apps and data storage on webpages of website servers. To have instant on, the runtime operating system is always hibernating in the non volatile sram. Do not load OS image from nand storage. Use compressed file systems in sram of operating system  and virtual memory(swap file system) to executing area of 16 mB to do internet data transfer. Use infinite library of sd cards for data storage of movies and music.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

My Sylvania netbook came to me used. Battery charge light was never on, but battery was fully charged or indicate good. good for 2 hours until I use USB connection for two devices on dvd(no drivers) and another USB reader(connected), Then the charge went very low. The netbook was not charging the battery.

But as I power off the WiFi and leaving the netbook on, the battery was not further discharged when netbook was powered by the AC adapter. The ac adapter seem to supply enough power by the electrolytic capacitors. The keyboard light now worked after boot. But still no red LED light to show battery being charged, Will continue low temperature annealing to try restore the charging circuit semiconductors back to life?

This usually takes two week of not doing any functions just leave power on to cook the circuit. It does not indicate any tendency to fail, so it should cure the dried up capacitors and anneal the battery charging circuit at the same time, Dried up capacitors need battery power to aid surge required when you run the computer from AC adaptor.

This netbook needed a reset before image of OS will load. It does not have the latest OS image because of lacking some function in the control panel? So after 2 weeks of burning in, we will have to look at updating any software available from digitalgadgets.com.

If semiconductors were zapped(on/off switch arcing from inductance kick, good design uses capacitor across the switch terminals to suppress arcing), that means we have to leave it in the dark closet for one month to discharge the gates of cmos transistors, then anneal(any gate oxide fracture) for 2 weeks again.

Its interesting to note, that there is a procedure to charge the battery on the netbook. You must first connect the DC plug into the netbook. Then you connect to the AC power socket. This will prevent arcing when you connect the DC plug without 9 volts to arc, to the semiconductor charger input circuit.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Consumer electronics manufacturers are generally quality compliance and pay attention to 10 year old electrolytic capacitors(not to use) and current zapping problems of cmos transistor gates being shorted. Power input circuits are transient suppressed by condenser. Voltage is maintained by 1-10 microfarad condenser to prevent contact resistance change over time.

Inexperienced third world countries often have troubles designing quality electronics devices. Several brands are known for poor quality from China. Tablets delivered without screen(impact broken) protectors(adhesive taped), No transient suppressors on power input circuits are often major problems with dead on arrival catastrophe results.

This Xmas, many tablets and netbooks of $99 will have to be improved before they will stick(bought and kept). Returns are now too many as evidenced on ebay's parts for repair listings.

Re: Tablets $75 or less at CVS ? Netbooks too(Kmart $89) ?

Once the hardware of tablets and netbooks are safe from misuse of AC adapter, we only have software to worry about.

Microsoft WinCE is embedded operating system, we can not add much apps; but its perfectly simple to have a browser with flash player and active-x directory to work with all the webpages.

Android 1.6 then 2.1 then 2.2 and 2.3 made several levels of capability. Not all of them will work with your ARM hardware. So, do not upgrade and spoiled your hardware functions. Android versions are adapted by the manufacturer to have some special features. Newer Google android versions would not have special treatment done by the manufacturer of your hardware.

Linux operating system depends largely on version number dependency. Linux lovers try then give up or became a slave to fix all the bugs. Stay away if you don't have the patience or willingness to use only the sweet spots.

Microsoft windows may have autoupdate and backward compatibility, you don't have to work too hard to keep it working for you.

From the knowledge we have on file switching dependency, its difficult to keep changing functions and not run into bugs. The software as of a date code, has to be locked down, including browser functions for internet webpages.  The concept of alpha, beta trial for bug fices, by open source, is not feasanle, because of lack of quality control by a mere maintainer. File switching involves many apps using the same codes or files.

The attempt today is to limit the functions in a webpage with its own operating system by javascript on the webpage in simple computer hardware. Not using other files in any library, limits bugs galore appearing every where. Data in the webpage server is very simple database. The webpage has to be locked down on graphics and text, active-x directory and mpeg4/h.264(pixels) for many years. Then quality control is more traceable for many inspectors to sign off. People think webpages should change its looks frequently, is asking for bugs galore. Its more important to have data integrity maintained.

Tablet and netbook designs are simpler architecture to make operating system in webpages simpler and more compatible with enterprise servers.

Netbooks are still attractive for typists; Tablets are for phone people on internet for entertainment. Typing on tablets are at best chop stick style, or one finger only for short compositions. Bloggers may need a futuristic data compression software that behaves like Google instant search. Words(from a dictionary with phrases) appear before you finish typing to speed up your blog composition. Your next character input will change the whole sentence to your liking.

Someday, the tasks will also be reduced to one icon clicking to answer by formed letters. Which is a fine way to relieve people of the task of typing just to reply a question. Some tablets uses a stylus pen to dance on the touch screen that can speed up data input.

Most people wanted to do their work the old way with legacy software(dynamic memory requirement 4 gB). This is not possible anymore, because of webpages being the basic input and output format. Most enterprise data centers have to hire programmers to do webpage software creation for their database input.

Only kids can be satisfied with tablets and netbooks, because they don't have any legacy needs of older data formats. They have small hands. And they need entertainments more so than adults.software.

To perfect the use of tablets will take a years of design decision making. Netbooks maybe perfected sooner because of keyboard and mouse input system, people are used to.

Tablets' claim to fame is instant on. But to save bettery for even longer life, is to shut down WiFi radio(upto 1 watt power) if you don't need it to communicate. Then you double click to turn on Wifi radio to logon gateway router to send TX packet and receive RX packets until checksum is satisfied. Then radio is off again to save battery power.

Footnote:
Android 3.1 is reported causing many crashes on Chrome browser(lack of memory), mostly because of website selection of mobile webpage or XML webpages. The preference should be on crash back to mobile webpage to use less memory(256 mB and swap). To try for XML webpage you need vga not hdmi. You could do a conversion by data compression of mpeg4/h.264 to do hdmi webpages.

Google instant search can help you write blog better with more complete thoughts from search engine on the subject matter.
