What OS is that running? Mine is 3.5 (I think). I like the Palm mainly for a few games and reading. I used AvantGo, the web browser, at one time, but it was so slow and all that I just decided that the Palm was not too good of a thing for web stuff.
For reading, I used to hit Memoware...
http://www.memoware.com/Memoware has a bunch of Gutenberg like books and all availible for reading on the Palm. I have a Windows program that will convert ANY TEXT FILE to a Palm readable doc. I played with it some and managed to get it to make docs that didn't line break weird.
I nailed that Tetris... thanks for the heads up! Also nailed Video Poker and a Chess game. Reinstalled my Vexed game and BJ's Blackjack.
The games plus my Docs of Frankenstien by Mary Shelly, The Jargon File by Eric Raymond, The Hacker Crackdown by Bruce Strerling, and Approaching Zero by Mung and Glough should keep me busy nicely.
