Picked mine up yesterday at Sprint. So far it's been great. The hardest part is moving from all the non sense (pun not intended) stuff from having 3 straight HTC phones. Couldn't hack touch wiz, so I went back to Holo launcher. Much better IMO.
One other thing that is seemingly difficult is the physical button and no multi taking button... now I have the menu button back. :-)
Also... long press the home button will give you the multi tasking button for open apps.
