Samsung has add its own TouchWiz UI to Android along with it's 3D cube interface. this could be a good or bad thing depending on how you feel about the touchwiz UI. TouchWiz has been changed slightly, including a larger widget box that replaces the stock Androiud App Tray. The dialer has also changed from stock Android and i think it's an improvement. Also the SMS app, photo albums, and most importantly Samsung has replace the Android Camera interface with its own, much better, camera software. It does seem at times that touchwiz can make the phone a little more sluggish than it needs to be and takes a fair amount of processor power. Cube is cool, looking, but slightly gimmicy. It does have a very nice coverflow like feature for viewing photos, youtube vids, and scrolling through your music albums, not to mention quick access to Amazon Mp3 store. All in all it's a very nice looking UI and lets not forget its Android if you don't like the UI you can always root your device and run a basic version of Android.
