I got my 360 elite in 2007 and it only failed the day Mass Effect 2 came out (Crashed during gameplay) and due to the error being an E74 error I had it fixed for free and no problems since.
So in all I have had the 1st 360 I ever owned.

Had the original then it got the RRoD so I got it fixed then it started to stop reading my disks. So in like 2010 I got the slim and no problems ever since.
