I ported plan9 to the sharp zaurus SL-C3100. The SL-C3100 is a very cute pda device with a 640x480 touchscreen lcd and a qwerty keyboard which I find just about adequate for doing a bit of programming with when out and about. Sadly, it is no longer made.
Not sure if I can post urls, but there's currently a picture at this location: http://server.hemiola.co.uk/zaurus.pdf Rod
