This is like antenna gate-- typical Apple bashing pretending like there's some sort of defect when there isn't. And like antenna gate, if you analyze other phones on the market, you'll find they too don't have super human strength.
In fact, the fact that they bent, instead of breaking, is pretty strong evidence that they are the best built phones on the market.
Subject any competing phone to 300pounds of force differential between the center and the edges (or whatever they used to get these to bend) and I'm pretty certain they will be destroyed.
One of the reasons I buy Apple products is that they are built to be durable in a way that very few of their competitors are.
