XBOX 360 with Kinect

Further proof no one listens to me, not even my XBOX!  I tell it to play, pause or whatever and it completely ignores me!  What's next my iphone 4 won't make my calls if it doesn't like who I am calling?  I really want to master my technology, it frustrating when my machines that are designed to make my life easier only succeed in making it frustrating.  I am still trying to figure out how to delete stuff off my iPhones iPod, I miss the blinking 12:00 on my vcr, now THAT submitted to my will!!!
