(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)
