I've got a windows pocketpc PDA that I use for reading ebooks and web surfing in wifi zones. Its getting worn out and I need to replace it, but PDAs seem to be going out of style and it looks like I'll need to get a smartphone instead.

Smartphones all seem to have tiny screens compared to dedicated PDA, pathetic battery life, or cost £400/$550, which is twice the price of my PDA which I bought way back in 2004.

Any recommendations?
