When I lived in college dorms a few years back, my thinkpad would fall ~6ft out of my bed onto tile a few times a week. Occasionally I had to pop the battery back in.

Plastic can flex to absorb the stress without permanently deforming, aluminum not so much. Even the panasonic toughbooks are plastic, and those are probably the most durable laptops I know of by a large margin.

Interestingly enough destroying a Panasonic Toughbook is easy. Stand on it with high-heels... The Panasonic rep had just been stomping on it, and then this smallish woman asks if she could try.

It didn't boot or do much of anything after she had traipsed all over it.

That being said, I am not saying the MB would fare much better, but those Toughbooks are not as tough as they are advertised.
