Pocket PC Crisis

I don't know what kind of technology I want to buy to take with me. Right now I am leaning towards a handheld pocket PC with these features: lots of memory for my word files and contacts, MP3, voice recording, Wi-Fi, and possibly camera. I really like the PalmTX, but it doesn't have a microphone, nor is there a microphone attachment for it - this makes me mad. I need to be able to record interviews. Also, no camera capability, though I am leaning more towards carrying a separate cheap and small digital camera. Problem is I HAVE NO SPACE on my body to carry all of these devices. I need 1)word processor/file carrier 2)MP3 player 4)cell phone 5)voice recorder 6) camera. I would like to consolodate at least three or 4 of these into one device.
Another option which lots of techies have been pushing for me is something like a Treo650 or IMate K-Jam which can double as cell phones. I have issues with the cell-phone PDA combination though, one being that I don't like to carry all my files with me as often as I'd like to carry my cell phone with me in a scary foreign country. Another issue is finding compatible service abroad: while the Treo650 would require me to buy a plan over there, the IMate apparently would just need a SIM card (please correct me if you know better, I have no idea how these things work even though I spent all day researching this). If I go with one of these cell-phone type things I will go with the IMate since I really like the design and it has a camera and voice recording, and this dude offered me one for half the retail price.
I welcome advice on this matter.
