Loving the new Smart Glass App on Windows Phone and Windows 8 -in no time it has become my preferred controller (for non- gaming scenarios) split in equal measure between Windows Phone & Surface RT device.  

We have an XBOX connected to a large screen TV in our lounge and slowly but surely the XBOX is overtaking all other devices (don't ask) as the preferred media source/player.

Great job guys!  (Hope those rumours of a 7" XBOX gaming device with all this goodness baked in are true).
