I just hope this doesn't inspire people to really shake the macbooks so hard to cause a disk problem or any other hardware issue.

I advise you add a disclaimer for this? ;)

That's actually why the sensor is in there in the first place: to let the hard disk shut off if it detects that the laptop is falling.

It actually makes the HD parks the heads out of the platters in a really mean way. It's better than having heads collide with the platters but it's a wear sensitive operation designed as an emergency countermeasure. Doing it repeatedly on purpose is certainly a bad idea.
