1. Activation was far less than seemless. Could not update roaming via any method for a while. Then it took but after a reboot same problem. 2. It is somewhat faster but you would have to have them side by side to notice a difference. 3. No Netflix 4. When I open a web page it gets 90% done and then blinks before it finishes. Annoying. 5. Slow to awake when you hit the power button...noticable lag, bothersome to me. Positive: 1. Screen is more than 25% better. More like 75 %. Brighter and more contrast. 2. Uses same batteries and accessories. 3. Umm, that is about it. I am sure root, rom, updates, GB and other things will make it a great phone, but not right now. For me the original X is still tops.
