I just bought 2 of these to upgrade my wife's phone and mine from a V3 and a V557.  What a difference!  Lots of features: mp3, video, 1.3mp camera, etc. I found a shareware video converter online and have put some videos onto the 1G microSD card (be sure to get a microSD card for it).  It plays great and landscapes to use the whole screen.  Another must:  If you're going to use the internet and video features of this phone, be sure to get an unlimited data plan, or you'll be paying a bundle.  I used 15MB+ the first day on mine just playing around with it.  Even with the unlimited data plan, be careful - using some features (XM radio mobile, HBO, etc) will be billed as content.  Overall a great phone and easy to use after a couple hours learning all the features and menus.
