If you're still looking for a surplus steal in Tablet PCs, consider the Fujitsu PenCentra 130. For less than $120 from
HSC, this handheld PC comes with Windows CE embedded in ROM, stylus, battery, memory, dock, keyboard, and carrying case. Don't expect to load Windows CE applications and games on this PenCentra 130, though. The embedded OS is very finicky, but this sampling of Windows CE-MIPS-formatted products should get you started:
Bubblets and
Tascal Registry Editor. Also, a recent
HPC:Factor forum posting by HSC suggests that the memory module might not be available anymore.

Comes with stylus, battery, 2 screenprotecors, and AC Adapter. No documentation. User Guide PDF from Halted page. Mine has 7 hour battery life. YMMV.
