I really didn't want to get another motorola as my original X was giving me problems. I got impatient and hooked up with the X2 today.
So far it is snappier but most phones are before loading in all my apps. The screen has almost a blue tinge to it compared to my X and my friends Incredible 2. Text is sharper with the qHD screen over the X. Video recording appears to be MUCH smoother as well as being able to zoom WHILE recording. The camera focus is better, but I still find the pictures lacking in depth and detail. I just came from running Liberty Gingerbread on the X and noticed many Gingerbread elements in the moto UI even though it is 2.2
Otherwise same size phone, sans camera button, fits in orig. X case. Uses same BH5X battery. That is all I can think of for now. Going to load up some of my apps and hope everything stays smooth.
