Who invented the first tablet PC?

The invention of the first tablet PC, or personal computer, is credited to three men: Alan Kay, Steve Jobs and Bill Moggridge. Computer specialist Kay created the concept for the tablet PC in the early 1960s, which he called the Dynabook, but need technical expertise to build the product. Technical enthusiast Jobs analyzed Kay’s product in the 1970s, and lent a hand in determining the components needed to build the machine.

It was not until 1982, however, that the first tablet PC was assembled and introduced to the public. The inaugural PC was designed by British designer Moggridge, who unveiled the PC in a sharp black shell, and with a hefty price tag.
