Mine died a months and so ago. I think the problem was because I moved house and just stuck the xbox 360 on the carpet underneath the TV which may have owned it. I am thinking this becuase we also used my friends xbox that I am living with and it got the rrod as well. I replaced mine, and am keeping it on the table with the TV this time and its working fine.
That xbox lasted 2 years before this though, and was one of the oldest onest (bought it 2nd hand). So I guess if you treat an xbox nicely it won’t error on you. I don’t mind that it died as now I have a thuper quieter one and HDTV which the old one didn’t have. Only cost £60 to replace as I had all of the accessories.
