Retina Display MacBook Pro Doesn’t Get Hot?

This post refers to

Jim Dalrymple on the MacBook Pro with Retina Display:

I tried to get the MacBook Pro to get hot enough to turn the fans on, but after a few hours of using it, the fans have still not turned on. Or if they have, I haven’t been able to hear them.

Amazing. A lot of people were worried about how what the heat would be like on this thing. Apple really knows what they are doing.
