Dynabook is a brand name used by Toshiba for its line of laptop computers. The dynabook name was first used in Japan in 1989 for Toshiba's J-3100SS laptop computer. The term "dynabook" was coined by Alan Kay in 1972 to describe a hypothetical future laptop computer. His concept envisioned it not just as hardware, but more of as a tool for education and collaboration that was easily accessible via network.
