A Tablet computer or a tablet is simply a mobile computer, with a flat touch screen and virtual keyboard as in our androids or iphones, one can do a lot more in tablet than in a computer, it has wifi, bluetooth and USB support as in your computer, a tablet design was given first by Alan Kay in 1968, the first tablet came in to market in the year 1989 manufactured by well known Samsung for GRiDPad Systems Corporation, well it is successful that is even used by the US Army, the specs are as follows :
It measured 9x12x1.4 inches and 4.5 pounds, it had a stylus pen with which you can calibrate touch and it also had hand writing recognition, it contains :
10Mhz 80C86 processors
MS-DOS operating system by IBM
Color Graphics Adaptor with display of 600x400 pixels
256 or 512 KB RAM
1 or 2 MB of System memory
I would say that's a good configuration of that time, well the memory is somewhat low, but they did it first.
The GRiDPad.
A tablet is just a hardware equipment that which can run with the help of different Operating Systems.
After GRiDPad, the ACORN computers developed an ARM machine with a touchpad and named it NewsPad, after them INTEL developed a stable tablet with the help of ARM in 1999 and named it WebPAD.
In April 2010, the well known Apple, released the IPad, having IOS on board, the great thing about IPad is it's design, it's so sleek and Steve Jobs is man who always considered the design and reliability also thanks to Jonathan Ive the designer of Apple's products. Also Apple released the IPad2 which is 15% lighter when compared to the first and has a dual core processor of Apple A5.

However the configuration is not so good, the camera doesn't have flash, many things are forgotten in this IPad
The tablets are soon released with many operating systems like IOS, Android, LINUX, BlackBerry RIM (Research In Motion) and so on.
But nothing made sales like IPad, Soon Samsung which entered the Android market then developed the tab called Samsung Galaxy Tab, both Galaxy Tab and IPad fought.

Among the tablets available in the tablet market in 2012, the first place is occupied by Apple IPad having sold 100 million sold by mid october 2012 followed by Amazon Kindle Fire with 7 million sales and followed by Barnes & Noble's Nook with 5 million sales
Reliance Tab available in INDIA is economical which is available at a price of nearly 12,000.
Samsung Galaxy Tab is available at a price of nearly 29,000
Having a tablet is most advantageous than compared to an Android or Laptop, it is portable, flexible and more to come.
I would prefer to buy a Samsung Galaxy Tab if I want Android flexibility and Application reliability, I would prefer IPad if I want to go with design, quality of pictures, pixel density, media, however applications are more in android than in IOS, but IOS is more organized when compared to Android. So users decide what do you want?
Thank you........
