I upgraded from the Epic 4g to the Evo 3d, best decision ive made with phones. the UI is soo much better then the touchwiz. My wife has the evo 4g and its so slow and clunky next to my phone. she likes to steal it every once and awhile. i wish ppl would stop saying the 3d is stupid. THE PHONE IS NOT IN 3D! only the pictures/videos that you take in 3d mode are 3d. i do find myself seeing objects in a different way though. when i take pictures now, i try to find cool angles to get the most out of the 3d part. you can convert the picture to 2d with a click of a button. btw i didn't buy the phone for the 3d, i bought it because its a quality phone, dual core, and guaranteed to get ICS when its comes out and sense 3.0 rocks.
