I own a GRiDPad 1910, upon which I run PC-GEOS 2.0 with Graffiti. I wrote a Guide to installing GEOS on the GRiDPad 1910 which will help you get to the same place. Once it runs GEOS, it functions as sort of a giant PDA. There's a great deal of old PC-GEOS software which can be run on it, and it has a 640x400 monochrome CGA display.
