Ignoring the general hardware fault had my vote
my first 360 was fine for just over a year then BANG RED LIGHTS

sent it off to be repaired (not to microsoft)......................still not working ! (no warranty at the time)
Bought a second flashed it got banned

So now i have 2 useless 360's i cant imagine how many consoles have been sent off off or had some sort of
diy fix attempt.(which could have been prevented if microsoft had grew some balls back then rather than 1.5 years to late.
Should my first 360 be repaired( doubtfull) i will stay on live if not my next purchase will be a ps3 along with the 5.99 a month to have piece of mind ....if your console should break or get dropped etc you have a new one almost straight away, so what i was spending on live will be spent there now.
I had a great time on live and had a few good friends on there
