I'd like to use it as an ereader, for internet surfing and email, watching videos, preferably in avi format, so I don't have to convert them all to another format, but having to do that would not be a deal breaker.
I'd like a somewhat larger screen, so it doesn't have to be pocket size.
Good battery life, and user replaceable battery if possible, plus expandable storage.
And the main thing: I can't afford much, so it'll probably have to be something used that's been around a while.
Does something like that exist?
I've researched a bit, but every time I think I've found it, there are some problems reported that make me step back and start looking again.
The ones I've considered are: Dell Axim v50/51, HP Ipaq 210/211 (probably can't afford it), Palm TX (a little too outdated for internet use, I think), Archos 5 (sounds very unreliable), Smartq 7 (same as Archos).
