I don't have any solid numbers on me, but I believe early 360s failing wasn't just widespread; it was straight up most of them dying within the first couple years. It's honestly insane they more or less got away with that. And I guess also speaks to how much Microsoft was killing it in that era that people were willing to go through multiple console RMAs (which I heard was a terrible, slow, and unreliable process) to play 360 games. How far they've fallen.
I knew plenty of people who had rrod no one swore off xbox though. You were still in the ecosystem through games, controllers, xbox live membership, and in my case network effects since we all played halo.
