Work just bought me an iPaq. I was happy with my Handspring Visor, but who am I to pass up free hardware. I am amazed at the derth of good software for windows CE in general, let alone D&D stuff.
The most useful thing I found on the Visor was the tomeraider monster and spell databases. Now if I just had something like that I could update!
I should just grab a beer and start hacking perl to generate some nice web pages to load into pocket IE...
