If anyone doesn't know, my X360 bricked in March, and got replaced in 10 days for free. Anyways:

I noticed one thing about this new one: thus far, it hasn't frozen once. On my old 360, and the older ones too, once in awhile (a great while), it'd freeze. I think it froze on me about...2 dozen times over the length that I owned it.

However, since I got it back, it hasn't frozen once, which is kind of odd to me. Does anyone else have (or had) any problems with their old(er) 360s freezing? It wasn't a big issue, as I never cared, but I have noticed it's never happened thus far.

well i had a launch 360 it was fine until i started playing rainbow six vegas last year.. for some reason it started to freeze all the time when i went online... it bricked on me a month later so yes i have had problems with it freezing on me... i think it was the game that made it do that but im not sure..

Well my original 360 unit played fine. While I'm on my second 360 my first unit never got the RRoD. I had a faulty disc tray, it refused to stay closed. Even when I turned it off, the disc tray would slide out before powering down. Everything else about my original unit was fine, all of my demos and XBLA games worked, but I couldn't play any of my disced based games..
