iOS 7 foregoes borders, instead relying on colour to indicate interactivity Good thing there aren't people out there who are color-blind, then... Oh, wait.
That's me! I was browsing the new UI guidelines and couldn't understand what was and what wasn't a link/action in the screenshots that they used for examples! And I shouldn't need to turn on accessibility services for slight colorblindness... the design should accomodate for us. The navigation looks lik the same color as the "Home" and "Phone" labels. Are those actions?
My experience of Windows mobile is Windows 8 on a tablet, and I had pretty much nothing but contempt for it. And failed to see anything stylish about it at all!
I want links/buttons/actions to stand out. That doesn't mean it has to look like a button. It could be text with a halo, a shadow, or an effect that comes into play as you begin to interact with the device so the controls jump out at you, or are overlayed or something. Don't just present raw text at me. Though having said that, I'm sure Apple will make it work, where others haven't.
iOS 6 looks pretty infantile by comparison, but the new screenshots and icons don't look that nice or that cohesive either.
(I was hoping that they might just drop the old school 'i' from iOS and just call it Apple mobile OS or something, it grates my ears and eyes, the name is like soo 1999.)
The thing that I notice from the stills is that the typeface appears quite weak. I had the same issue with Windows 8, my eyes just can't read it comfortably, I'm not sure why that is - and it looks more diluted now - and there is less contrast in general. Though perhaps it will look okay on a retina display.
