Come on, these things happen!
When Forza 2 came out it bricked my 360, great. Lets be realistic, MS build quality is (to politely put it) poor. I dont know anyone that hasn't owned at least 2 360's. The point is the software is good, Forza 2 was good, halo 3 is good, if you're put off by a few manufacturing issues..... I'm prepared to overlook the poor manufacturing to play good games!
