This would happen to me...
Like many of us XBOX owners, I've had a RROD before. The first was taken care of by MS in the early days, no issues. A few years later I bought a second system for my household, the older black Elite, and it succumbed to RROD after the warranty expired. I replaced that with the Slim Elite model without second thought. I play the system frequently enough to justify it as an entertainment expense.
Today I see that Best Buy is offering $100 system trade in credit! Woo hoo! I still use both systems daily (Old Elite for Netflix/Workout videos in kids play room and the Slim for gaming in main living room) and when I went to workout in the kids room, this older, replaced system just RROD. @!#$&*@!*^! There goes a hundred dollars I was going to use to towards XBOX One, literally tomorrow.
I'm ready for the next gen and am glad to get past 360, even with the thousands of hours I've put in it since day 1. Friday can't come soon enough!
