I got my first one around February 2006. I cannot remember when it died on me, but it had to be more than a year after. With my first console, every game I owned -Except Sonic 06- had frozen on me at some point. Gears of War would freeze on me like every chapter even.
Microsoft replaced it fine and it only took three weeks to return, BUT the one they sent me would scratch my discs (!!!), so I got really upset because it was about the time Virtua Fighter 5 came out. Microsoft also replaced this one fine and they gave me some Microsoft Points and Xbox Live Gold months, so I did not complain too much.
My newest one I have had since SEGA Superstars Tennis came out (I remember because I had the game like five days before I could play it :cry: ) and the second I turned that on it froze on me (!!!!!!), but I have not had a problem ever since.
I got a Wii a few years back expecting it to be as trustworthy as the GameCube, only to get the same issues, and in many cases many worse problems.
I have heard a lot of really, really bad stories about the RRODD, but personally I have not seen many of my local friends have any kinds of issues, at least nowhere near as bad as they have had with their Wiis and PlayStation 3s. Microsoft has always replaced everyone I have ever seen with complaints and I never heard of any issues yet with the Xbox 360 S, so these kinds of issues are clearly dying out. Nintendo and Sony are also getting better with their models and replacements, so I am not as worried as I was two years ago.
