on the tool analogy :

only the biggest POS tools have bad ergonomics on the industrial side. The real quality tools, the ones meant to be used on the factory floor or in a production line, think of human ergonomics first .

I would probably be considering that as I took a file to my laptop in order to keep it from cutting into my skin as I used it.

I applaud the ingenuity, but I detest the concept of aesthetic-first engineering without a thought for the human user of the thing. Vote with your dollar.

In the case of parent : I admire your ability to cope and the chutzpah it took to take a file to company property.

on a side note : I think it's absolutely fascinating in every Apple thread watching users trade tips on how to avoid electric shock, electrolytic/chemical pitting, and skin cuts like it's just normal computing worries. You folks have some thick skin to keep at it. I would be rubberizing the whole damn thing after the first zap.
