In that case, Apple should engineer the phone to be waterproof and and to be sprayed down with antibacterial spray and wiped clean since we all know that people use these things in the bathroom and that plenty have dropped their devices in the toilet.
As for the thinness, I agree, I wish they left the thickness the same as the iPhone 5/5S, and just made the battery bigger (for the 6 and the 6+). This would have not increased the thickness that much so that it was still able to be held in one hand, increased the battery life even more, and eliminated the protruding camera ring on the back, which doesn't bother me that much really since I put a case on my phone each time anyway. Have a Bodyglove case and a Spigen Thin-fit case for it so the size is already there anyway (for my 6+). Mine is able to be in my thigh pocket and not get bent. I also usually wear cargo pants or short so plenty of room in there to fit the Plus.
