PDA-type gadget thingies

[SaraAmarie]

I think I need one! lol But I'm not even sure what to look for or where.

I would mainly like to use it to:
*Read .pdf/.doc files (like digital books for traveling)
*Look at photos (be able to plug an SD or xD card into it if possible)
*Listen to music
*Surf the internet

I don't need phone or camera capabilities in it.

If anyone knows of something that would fit what I am looking for, please pass on some suggestions.
