I feel for you. If you hadn't already sent it in, I'd say return it to the store and buy another one. That's what I ended up doing. After multiple calls to MS, it simply came down to the fact that no one could tell me when it would be replaced. That is not acceptable when you buy a companies premier product. When other people are receiving new orders placed weeks after we sent ours in for repair, it shows that MS doesn't care about you once they get your money.
