FOREVER!.....or until it dies.
every since i've modded my box and dropped a 300gb hdd in it, i'm truly starting to enjoy what the potential of a modded box has to offer.
the 360 is only better than a modded box in 1 way...it plays 360 games. other than that, a modded box is far more superior right now. the capabilities of the current 360 is so limited and costly that i'm not even interested in whatever media center potential that it has.
even after we hack a 360, i'll still use my original box for a media center.
