Dynabook

The KiddiComp concept, envisioned by Alan Kay on January 1, 1968 while a PhD candidate, and later developed and described as the Dynabook in his 1972 proposal "A personal computer for children of all ages", outlines the requirements for a conceptual portable educational device that would offer similar functionality to that now supplied via a laptop computer or (in some of its other incarnations) a tablet or slate computer with the exception of the requirement for any Dynabook device offering near eternal battery life. Adults could also use a Dynabook, but the target audience was children. Though the hardware required to create a Dynabook is here today, Alan Kay still thinks the Dynabook hasn't been invented yet, because key software and educational curricula are missing. When Microsoft came up with its tablet PC in 2001, Kay was quoted as saying "Microsoft's Tablet PC, the first Dynabook-like computer good enough to criticize". In 1989, Toshiba released a sub-notebook computer called DynaBook, inspired by the concept. Kay was personally gifted a unit and was a guest of Toshiba. The company released notebook computers under the DynaBook brand in Japan; in 2018, Sharp acquired a majority stake in Toshiba's PC business, now named Dynabook Inc. and has marketed notebooks worldwide under the Dynabook name.
