PSA: X1 Owners - mount your kinect on top of your tv
Just did this today with a TV mount I bought from Best Buy.
Improved the voice control considerably and the gesture controls are now nearly flawless to use. The big benefits for voice control are mainly getting the microphones away from the TV speakers so they can hear your commands better. The gesture control is now actually usable in this position.
Huge step up from having the Kinect mounted on the base of my TV stand. Highly recommended you try it if you can.
