I agree that the Pilot is a great form factor for portable chess.  You'll never
see a dedicated portable chess computer like this though, because the cost of
the high-res touch-sensitive screen is too high.

Your program is PocketChess.  It is based on SCP, an old public domain program
which is the forerunner of GnuChess.  Its strength will be limited by its
primitive eval function and the 17MHz processor in the Pilot.  I've heard
estimates of 1700, but I believe that is too high.  The same search engine is
incorporated into Deep Green, which runs on Apple Newton MessagePads.  Deep
Green running on a 160MHz MP2000 maintains an 1800 blitz rating on FICS.
