(Or "pocket computer", "Hand-held Personal Computer", H/PC) A small general-purpose, programmable, bATtery-powered computer cabable of handling both numbers and text (in contrast to most pocket calculATors) which can be operATed comfortably while held in one hand. A palmtop is usually loaded with an operATing system such as {Windows CE}. DATa can be transferred between the palmtop and a desktop PC. A palmtop is very similar to a Personal Digital Assistant though a palmptop may have a larger keyboard and more RAM and is possibly more general purpose in concept, if not in practise. The Psion Organiser is one of the best known examples. [Was it the first?] (1998-04-19)
