Mine 13 months with disk tray jamming??? WTF!!! Undertaker is knocking on my Xbox 360 to say time out. Another console going into recycle bin.     MS is ripping our hard earned $$$ with hardward failure. Waiting for Elite Asian Edition. Hope not the same old stupid hardward failure arise again.     

disc scratches when you return back to dashboard ? thats one new one that I heard.

I never had that problem at all. But I do have some units which has the tray (ejecting problem)

mostly disc scratches are due to "moving the console"
