The idea of the laptop already came in the late 1960s with the Dynabook, but the Tablet PC, especially for children.
There was no real commercial incentive for a truly portable computers to develop, (and it was assumed in all cases impractical), it was not until much later, with new developments in transistors and processors, that the laptop has been viewed as something more than a child's toy.
It was in the early 80s, developed the first truly portable computer, theOsborne 1 had no batteries, (it had to be plugged in), but at least the data and computer could be transported.
