I have the Treo 600 and I like it. It's a little bit big for a phone but you get used to it and it's better than carrying a phone and palm. The screen does need to be cleaned quite often because it touches your cheek when you put the phone to your ear. The battery life is pretty good when your using the phone (about 3-5 days). But you can easliy kill your battery in a day if you play games on it. The screen does get a little bit washed out if you are in bright light. But cupping your and around it makes it visible again (this is only a problem in very bright light). My friends have told me that the buttons are a bit small for their fingers but I have no problem with them at all. And they way the keyboard is layed out I can type very fast on it.

Overall I give the phone an 9/10.
