Now that is just ridiculous. When you hold the iPhone on your ear, the edge touches your ear anyways. This mockup is simply changing where it touches the ear, which would be just a tiny bit lower on your ear than previous iPhones. And it's only uncomfortable if you actually push the phone into your ear.
You were really overreacting and didn't even bother thinking.
yeah but there is another disadvantage as well, and thats background noise, it will be much higher if only half of your ear is covered by the phone...
