What do I do now?

Okay, so I'm one of the last holdouts to the IPhone/Android market.  I've had a Blackberry for many years now and I've gotta tell you, it sucks.  I've spent more time lately waiting while the device gets hung up, stops working (or my favorite) make noises telling me that messages are coming in, but I can't access them.  Aaaaarrrrgh!  I've turned it off, I've taken the battery out, I've been to the Sprint store 6 times and still this piece of crap won't work.  Sprint Business Customer Service is willing to SELL me one of the new devices --- REALLY?  REALLY?  You're willing to SELL me one!  What do I do now?
