My windows phone 8X by hTC, just picked it up yesterday from the T-mobile store and its amazing. I spent all day yesterday setting it up and playing with it, don't have all my music from my HD7 in it yet but I do have some songs in my SkyDrive. The functionality and speed compared to my HD7 is night and day, especially the battery life. My only cons are that the low battery warning is now at 10% instead of 5%, I used to use it as a cue to plug in my charger. Another con is that when watching videos in the default player there's no buffering progress bar. Other than that love this phone.
