I'll be honest, the 3D renders looked a lot sexier than the "real" one. As someone else pointed out, there seems to be a gap (or uneven level) between the aluminum and glass parts of the back -- but this may be because it was assembled by iLab and not Apple's official partners. If, however, that gap exists in the real version also, the days of Apple perfection will have ended and would be time to sell my AAPL.
But I don't hate this design. The two-tone design on the back will take some time getting used to, but based on these leaked renderings, I still think the iPhone 4/4S design is much better than this. But that's just my opinion. And I'll still be buying this one.

And that small hole between the cameral lens and the flash is back. I'm intrigued as to what that could be.
