wats up with the red circle of death?

so the xbox360s i got for myself and serene's brother now suffers from the RED CIRCLE OF DEATH (similar to Window's blue screen of death, this involves the xbox360 and the power switch circle leds)

Waiyew borrowed my xbox360 previously and actually brought it in for replacement. The shop replaced it without asking a question. However the xbox360 faces the red circle of death again :( along with Eugene's xbox. So i had to call them to actually book a date where i can go down to replace the xbox360s. And i had to wait till AFTER 12th Nov (i called today).

GOOD LORD.... i know that the red circle has been happening to quite a few xbox360s.. doesn't this warrant like a recall of sorts for the faulty machines?!?! haven't we suffered enough of Microxxxx's incompetence ?

:(
