Over 2 years strong and going with my original 360. Though, I think that by modding it out with different fans with LED lights, new clear air ducting, and a plexi side cover, it aids it in running a LOT cooler and quieter.
I did read somewhere that it was speculated that 360s have a 16% failure rate. That is unacceptable. I wonder if there is any proof that their newest gen has remedied most, if not all, causes for the Red Rings.
