Ya these pictures are pretty weird. I like the squared off look on the iPhone 4-5S. So much cleaner looking. Once it is rounded, it looks more like plastic, like the iPhone 5C and all the android phones.
My only complaint with Maps is that there is no way to turn off "toll roads". I live near a toll highway and Maps tells me to use it all the time, and often there are no offered suggestions without the toll road used.
Other than that, it is great!
I'm not really liking these mockups personally. They seem to be more in line with all the other smartphones and not distinct at all. Now, granted they are all just rumored and what not. I like the square design of the 5/5S better than this rounded mockup. But, I still have 1.5 years left on my 5S so I won't be upgrading anyway.
If Apple wants a payment system, they should buy an already established one. I feel like Apple is trying to expand too far out. Instead, buy Square or something similar and just integrate it. Trying to build their own may not work out or take a while to gain traction
