(Edit: Didn't notice before, but this is mainly just highlighting one of the replies in the previously linked interview with Holmdahl.)
It certainly does seem to be a widespread issue. I now have two friends who have a bricked 360 outside of warranty, and one other who had a warranty replacement. (Yes, I know personal examples are not good measurements, but this is still WAYYYY above any other console issues the same same set has had, and the problem has kept up for a long period of time via online reports.)
I'm surprised there's no class-action lawsuit yet. ...or am I wrong on that regard?
Hard to keep up on lawsuits in the US. Hehe...
Is there any course of action my friends can take right now?
