IOS6 design - what's going on?

This is weak sauce. The first two screens look very similar to me, any differences are down to the special status of the dialer screen. The third is interesting and pretty.

Anyway, that's just trivia, the real point is that consistency is not the be-all and end-all of design. There's a space for character and diversity in design. Are any of those three screens difficult to understand? Are they ugly? Nope, they're fine. I don't see any basis for complaint.

The dialer on my old treo looked better. Am i the only one upset by this? Don't even get me started on the new appstore...

I don't see anything wrong. Could you describe your worries?
