Alan Kay published a paper related to this would be a tablet device and he called it 'Dynabook'. This future device's sketch is almost similar to present tablets but having some exceptions related to technology. Dynabook was proposed with both the screen and keyboard on the same panel side. He also predicted touch screen technology even on those days. In 1989, the founder of Palm, Jeff Hawkins presented GriDPad, the first physical tablet which was having a capacitive touch screen and wired stylus for interfacing. It was having around 5 pounds as weight. Thus GRiDPad was heavy, bulky and having short battery life and capacity.

But without the great vision of Steve Jobs, iPad would have not been possible and it would have not created such a long desire of tablets in the market. Today many companies like Google, Apple, Microsoft, Motorola, Samsung, HTC, Sony etc are trying to fill the expectations of the customer in tablet technology.
