Tyler, it seems you and I are the only two people that don't have their Matrixes move on them. I've taken mine to Oregon and back and it didn't move. I even took mine to Colorado and it did't move. But we will see on the return trip back home.
The only time my chip moved was when I took it to the east coast with me, it also moved on the way back... But I guess after a 6,000 mile trip, its gonna move.
But any way... When I get home I have to install three X2s and one of them in going in my XBox. Got my Matrix solder to a buddy of mine. I think I'm going to try and see him an X2 insted and keep my Matrix for a back up.
