Regarding the bending:
There's a video of a guy applying pressure directly to the center of the iPhone 6. People say that if you put it in your pocket, sometimes when wearing skinny jeans, it might bend your phone. I still think that this is a very case-to-case situation and that obviously applying direct pressure to the center of a phone using all the force in your fingers is different from sitting on it, mostly applying pressure around the entire phone.
I'm not denying that it shouldn't bend that easily when using your hands only, just saying that it might not have to be as bad as people say. I still advice everyone to be careful, though, and buy a hard cover to protect your phone ASAP.
