RROD stories are really bizarre - some people get them several times in a row, others have launch 360'ties to this day. I'm tempted to say it's a matter of the evironment the console's in, whether it's cooled or not, how much dust is in the air etc.
Mine is a weird case. It's a Best Buy refurbished elite I got as a gift, and I barely used it at all the first year I had it. Only a few months after I started using it regularly (by regularly, I mean a few hours a week at most), it randomly red-ringed. I turned it off, left it for an hour, and started it up again. No more red-ring, and no difference in performance except that it sometimes took up to a minute to truly shut off after pressing the power button (the fan was still running, etc). Now today, well over a year later, it randomly freezes within a minute of booting up any game (no RRoD, btw), after working perfectly fine for 30 minutes today, and for an hour a couple days ago.
I've always kept it in a rather open, cool environment, btw. At my old apartment when it red ringed, it was sitting atop the entertainment center with nothing above or around it, and now it's sitting in a shelf with a healthy amount of open space that's regularly dusted.
Anyway that was off-topic and my last post was mostly in jest, but for people who've had to deal with that, I can understand why they'd vote for the 360. I mean, how many of these other "worst systems" just flat-out stop working, and still cost at least $100 to replace, 9 years after launch? It's incredibly irritating, to say the least. Especially when the solution isn't as simple as, "Eh, I'll just upgrade to the new console, it's backwards compatible!"
