Lets not get way off topic, but the YLOD isn't the same as the RROD. The RROD affects a crazy number of 360s, maybe even as high as 70% of all systems made before 2010. To not get it is to have dodged a bullet. The YLOD on the other hand, is rare, and only occurs when all other heat-related countermeasures are exhausted.
I've had to heatgun my 2006 HDMi-free 360 at least two dozen times where as my day one launch purchase PS3 has never once had a problem with heat.
Again, I don't want to get into a fanboy-ish PS3 vs 360 rant here. The analogy was to compare apples to oranges, not the RROD to the YLOD.
