I bought the KRZR from sprint and it was pretty good at first. However as with any Motorola phone, the batter tends to fail after a couple of months and so does the actual phone. I passed that phone on to my mom and she has had to buy 2 new batteries in like a year which is ridiculous because I had used the same batter for 2 years on my LG Rumor.
Lets see; Camera is pretty good, it's small and sleek, it's sexy. The music player touch button things on the outside I found to be awesome. (I recommend getting the black phone). Text messaging was fun.
And like I said all of the motorola phones I've had do tend to fail. They freeze up and I've had to send them in to repair a few times.
