> If you can grab it by something you should be able to lift it. I disagree with this completely. I can pick a reasonable sized mirror up by the edge, and it has a chance of breaking. I can pick a table up by one of four legs, but it puts stress on the connections. I can pick lots of things up in ways that would do damage to them. And the people that made them _could_ make them stronger to avoid that, at the cost of a higher price. Or they could not spend the money and just say "don't pick it up in a way that puts unreasonable stress on it". It is a compromise and, for many items, there is a point beyond which it's not worth spending more money on it.
