[quote name='crazyj']About what percentage of 360's go bad? Is it mostly the launch ones?[/QUOTE]MS says 2-3%, but it seems higher. A newer one might have a slightly less chance of going bad, but there have been many reports around forums that even new ones will break down in just a few days.
I got a replacement 360 back yesterday. I had trouble getting the controllers to work with it first, along with getting it to recognize the HDD. After a few tries, I got both working. Well, I'm happy that my replacement is newer (4/1/06), compared to (11/15/05). I'm also glad to get a Samsung DVD drive, instead of that loud Hitachi. The Samsung drive isn't quiet, but sounds better than the Hitachi. So far, the 360 works, but I haven't tested out the USB ports.
