   <computer> (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?]
