PDAs just aren't useful to me, either as a tool or a toy. Foremost, the screen resolution is too poor -- maybe when 640x480 screens become mainstream I'll reassess the situation but up until now I've just hopelessly given up on 320x320 screens. Second, even though all these new PDAs have high MHz processors, when you give them a big task it seems my old Pentium classic was just faster at number crunching. Finally, call me foolish, but I'm reluctant to get my electronic devices "dirty", in the sense I would need to for a PDA to be useful to me in the field. I like to baby things, keep them in nice cases and such. I feel afraid of breaking the fragile screens on these devices by stuffing them in my pocket and what not. PDAs just not for me, and I've gone through owning several of them, both Palm and MS types.
