If it's to help the phone survive drops, then that's what they should talk about.
I can't imagine a reason I would ever want to bend my phone.
Now if I were planning on going to prison, I could see how a bendable phone might make it easier to smuggle one into my cell, but it's still not going to be very comfortable, going in or coming out. And god forbid I get a call while my phone is hidden in a body cavity. I keep my phone on vibrate and it could get very embarrassing.
