One of the reasons why many people buy a fender for their iPhone is that the back surface tends to scratch pretty easily, especially in the iPhone 5. Designer Matt Hughson envisions the iPhone 6 to come designed with an integrated aluminum outer frame, which creates a protective lip for the front & back of the phone. This provides improved protection for your screen & camera.
The cut away in the upper left corner gives the phone an added functionality in the form of a slot. This gives the user an attachment feature as well as lock-ability. The main screen maximizes the available space allowing for more wide screen view-ability.
