Report: New MacBooks running cooler

I just got this IM from a colleague:

I've noticed nobody has talked about how much cooler the new MacBook and MacBook Pro are on the lap.

I went to the local Apple Store and used several of them for over an hour using Logic and FinalCut Pro. After an hour the bottom of the unit was only mildly warm. The top was warm, but not uncomfortable.

Can you say "Thermal Mass"

I don't have one because I'm boycotting MacBooks with glossy screens, but I wanted to throw that out there. Anyone agree?
