I'm a film editor and avid traveller (just came back from a two week trip to southeast Asia) and I was thinking, "I should probably get some sort of PDA/tablet to use on the go." I've thought about getting a MacBook or MacBook Pro, but I just bought my iMac here and I don't have a lot of money right now. I do have a few old Palm Zires, but they're all dried up. Something with wi-fi would be nice, but not necessary. I don't necessarily need to edit on the go, either, but I do want to be able to make notes and stuff. Any suggestions?
