you're eventually right, the one thing which will break my ps3 will be the hdd, cause everything else failed.
i played on it next to a heater, had it sometime in closed cabinet, my little nephew used it as drum and it still lives. So i'm waiting for the day it breaks, meanwhile i sent my 360 to repair 3 f*cking times (and i just bought it june 2008)
i wish my 360 had only to worry about the hdd (no offense intended) :)
