Boards usually have a transparent coating, I doubt that it's only air separating the board from the chassis. For this very reason - laptops are thrown into the water as a test, they must not explode after that. I have never had a problem with a unibody Macbook. Please don't be ridiculous.

It's called solder mask and it doesn't cover the entire board...

Compressing the bottom of the case will short.

It's badly designed.

I think he's talking about conformal coating, not solder mask. Conformal coating can help but it's mostly there to prevent shorting across component leads from condensation. If you smash the Al casing against the board there's a good chance you can chip the coating and short things out.

Exactly, that's what I meant. Good point about the chipping off!
