So I pose the question to you guys, 'What do you do primarily with your Zaurus?'
Well, for this semester I'm on sabbatical, living in Spain (Valencia). My 3100 is my only computer. The Univ. here did have another machine available, but it is probably the least reliable Mac on the planet, so I don't bother with it. I use the Z at the office for browsing, e-mail, connecting to my machine back home for serious computational things, and writinf papers (with LyX and LaTeX). I then take it home and use it for basically the same things there.
After 3 months of it I'm fairly adept at typing on it, but I am also somewhat tired of the small screen. I do admit I long for a "real" computer, but for trips this is still the best.
