Got an Xbox One today and finally got it all set-up. I'm still getting used to the UI and figuring out all of that stuff, but there seems to be some potential for it to be cool if they do a good job of working out the kinks and rethinking some things. I believe my controller is broken, as the left stick click stopped working when I was entering some passwords for some of the video apps, so I'll have to get a spare soon and send the original in for repair/replacement.
I'm not a fan at all of the battery compartment on the controller, as I don't like that the batteries don't have any pieces of plastic in there to keep them in place.
