Switched from the Pre to the Droid.
I ditched Sprint and the Palm Pre because Sprint's customer service is like getting raped in the face with a power drill and Palm didn't really seem to care about putting out good hardware. After my second Pre started falling apart and reading so many reports about others having the same problem, I was done. WebOS is great, but Palm really screwed the pooch on the Pre.
I chose the Droid because it was solidly built, wasn't Windows Mobile and had a keyboard with a d-pad. So far it's the best phone I've ever used and the only phone that compares is the iPhone (which lacks physical controls and if I wanted a craptastic carrier, I would've stuck with Sprint).
