Tablet computing is older than you think. In 1968. Yes. 1968. Many of us weren’t even born at that time. It all started with Alan Kay, a computer science researcher at Xerox Palo Alto Research Centre (PARC). It was the first device to have wireless internet connectivity, something that we all take for granted today.
It had a 9-inch B/W LCD screen, built-in physical keyboard, an included stylus, ability to play songs and videos and weighed under 9lbs. (4 kg). All this was projected for a cost of mere US$500 in 1972.
The sad thing was, the product remained a concept and was never shipped. You can have a view of the tablet here:
