The KRZR is easier to hold because of its slimmer design. Plus, the features are better in every way but there is something to beware of. I purchased mine from Amazon as an unlocked phone about three month ago, and when I called about repairs for a small part on the back last week, I found out my phone was manufactured for sale in the United Arab Emirates and that phones headed for that country (or possibly others, I don't know) are "not" covered by Motorola's warranty in the U.S. And when I asked who I should call, presumably in the United Arab Emirates, I was told they didn't have a phone number to give me. Needless to say I was a little surprised to find out that one, I don't have a useful warranty, and two, Motorola couldn't provide a phone number for a different part of its operation. Very strange, especially since Motorola's website says "if it says Motorola on it, we can help." Well, apparently, that isn't true. So buyer beware. And by the way, the part that broke was the little loop that holds the lanyard. It isn't made of metal like the one on the RAZR. I had the back replaced by a local repairman for $30. Other than that, I love my phone!
