onscreen keypad on iphone/ipod touch takes some getting used to. I like mine fine, but it does make me grumble now and then (especially the autocorrect feature, which seems to have a very odd vocabulary).

mini netbooks are nifty, but I'm finding linux-based ones more difficult to come by these days. microcenter doesn't carry a single one.

I've never been big on PDAs. But I really do like my iphone. Granted, I don't like my monthly iphone BILL, but that's AT&T's problem, not apple's.
