< computer > (Commonly just "laptop") A portable personal computer of a size suitable to rest comfortably on one's legs. A laptop is smaller than a " luggable " (portable, but not comfortably) but bigger than a " palmtop " (easily carried in one hand or a shirt pocket).
Toshiba were one of the first companies to produce laptops, in about 1989.
