For all those continually complaining about the back of the phone design, may I remind you that the phone is a tool. As such, it should matter more how the device performs not how it looks on the back when most of you are going to have a case. And it's not like you will be constantly looking at the back when using the front, although a small few here will do just that.
It is a good thing that MR doesn't represent the norm of tech society. Otherwise, the world would be plunged into darkness just because of a camera bump.
