Neat idea.

Reminds me of a German computer mag in the 1980s, where they applied all 
kinds of endurance tests to joysticks like lassoing, bathing them in 
coke, fall tests from 1m and 2m heights, etc. Failing these tests 
resulted in deductions on usability grades as they didn't withstand 
"typical" accidents.
