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.

First one in 2007, replacements in 2008, 2009, 2010, and then the warranty expired and had to just buy a new one in 2011 which has been working ever since. And people will actually still buy the Xbox One launch year after that fiasco.
