I've had my Elite since it came out and i havn't got the RROD. 2 of my friends which have had their 360 for 2 years also havn't had it although 2 other friends have and now their fine with their replacements.
As long as the games are fine and replacing it is free i think it's not a problem if you like the console.
I'm pretty sure i will never get the RROD lol But isn't the RROD fixed for 2008 now? cases of it are much rarer.
