Yes, I know that the new MacBooks are supposed to have a recessed keyboard to protect the screen from being marred by dirt on the keyboard, but old habits die hard.
Awhile back I purchased a Marware Protection Pack for my MacBook, primarily for the wrist protectors. (The original white MacBooks can get pretty gnarly if you don’t keep your hands clean.
I found a new use for the keyboard cover today: heat protection.
Since the processor is located to the left of the trackpad on the underside of the machine, that section can get pretty hot and without a lapdesk, you can end up with huevos rancheros.
Simple solution: fold up that screen protector and prop up the MacBook with it. It’s still a bit warm and doesn’t provide any protection your “boys”, but at least you won’t end up with second degree burns on your leg.
