In 1968, Alan Kaya of Xerox PARC published the “Dynabook” document. The device presented in it was only an idea; it was not among the products that were to be sold. The project was described in detail by a Xerox employee or a compact device with its battery, hard disk, wireless connection, screen, and keyboard. The device had access to office, educational, entertainment, and multimedia applications. The purchase cost was to be very low, not just $ 500. Unfortunately, the project was not implemented and did not match the size of the existing machines, which were the size of the cabinet. However, despite everything, I will call this project visionary because it was only less than half a century later.
