That said, I haven't heard of one slim get the YLOD yet from my lurkings and Google searches. Some still have CD drive issues though. My new(est) model slim is running astronomically cooler than my Phats did, so I'm a little less worried than I was with the refurb.
Thanks for putting my mind at ease. The freezing has occurred across a wide variety of games (Valkyria Chronicles, 3D Dot Game Heroes, Uncharted 2, Infamous, Costume Quest), none of which are known as "buggy" games as far as I'm aware, but no more than once or twice for each game. I think I'm fairly lucky in that I never hear my PS3's fan, and it never seems overly hot, though I do keep it on a completely open surface.
For what it's worth, my brother got his launch model used off ebay like three years ago, and it's still going strong. Good to know what to watch out for, though.
