I vaguely remember some UK computing magazine tested a toughbook. They did the usual this is the machine, this is what it looks like and this is the specs but they also did a test on how robust it was.
Can't remember all of the tests and and when exactly it failed but they did dropping it, throwing it and running over it with a car. The final test they did was to have a Challenger tank run over it. Unsurprisingly it came out completely destroyed.
