Well I have a Sony Clie PDA, It has infra-red bit at the top (and with software) allows you to change stuff on a TV with i-r.
It has a Sony MemoryStick slot at the top near the i-r.
Bulit in VGA camera.
It runs the Palm 5.0 OS, so it has like notes and to-do list etc., notes would be good for putting/typing (well using graffiti input) stuff in.
Hasn't really got much to edit photos, probably none. (You could download some apps and Hotsync them to the PDA).
Well I think Sony stopped making PDA's but you might find one on eBay
Well, you can always get a similar Palm PDA with the Palm OS installed of course.
If it's already a palm, can't you perform a Hard-reset to restore it with it's default apps etc.
