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.

I still have my first black one from a bajillion years ago. The faceplate is white with scars and scratches and the rest is black with skateboard stickers. I keep it alive by dusting the fans semi-regularly and making sure the all the holes are not obstructed
