And I'm loving it. It's easy to pick out weak points and be nit picky.
I find the kinect and voice commands to be very nice, the Game DVR is a step in the right direction (I think they need 1080 suport and the ability to record longer).
I really wish the friends/social app was up along the top front UI between HOME and STORE.
Right now I'm pretty frustrated with Battlefield 4, but that's EA/DICE's problem not MS. And Forza is spectacular (visually and gameplay, I hear there's a fix for the economy).
It's also awesome that my wife/friends can make their own accounts and piggy back off my XBOX LIVE.

All in all, I am very happy. I'll get even more excited when Battlefield is patched and Titanfall/Destiny are here.
