Love my Treo
My first one ever and I have to say that I'm pretty impressed and glad to have it. I had a Body Glove case but had to quickly ditch it and get a pouch. I like the feel of the phone much better that way and the touch screen is much more effective. Added WizBar2, some games, my own program breeds, and some productivity stuff.
As far as the phone vibrating every time you sync that's a setting in the sounds where you check or uncheck the vibrate option for active sync. It might even be the e-mail. I found that if you have it check email automatically it'll vibrate or beep or both throughout the night until you check these messages. I finally turned off this feature because it was draining my battery (every time it does this the phone briefly turns on).
