Lately, I haven't noticed nearly as many people talking about RROD on any of the game forums that I frequent. I've also noticed that it's less common to read about it on news sites like Joystiq.
Do you think MS has finally gotten a handle on the problem, and the repairs/refurbs are working more reliably now? I got my 360 back a couple months ago and it's been working great, and I've noticed it runs cooler and the disks aren't so hot when I take them out after a few hours of use like they were on my old unit.
