(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.
