I think if they made it a little thicker to be able to get the speaker, mic, and headphone jack in and would also be able to get the silent switch on the side in that case like normal, this would be perfect. I would love that to be the next iPhone, it is dead sexy!
P.S. I like the light bezel, but make it a hair thinner! Oh and the back would have to be some sort of laminate or treated polymer because real metal won't bode well with the antennas inside. Last thing, the square on the home button needs to be smaller.
