Hi, Thanks for your thoughts! I agree with lots of them. Apple always wanted to unify all platforms - here is the next step.

Every company want to differentiate from competitors, and it looks like thanks to the new detailed skeuomorphic icons we will finally admire retina displays more ;) However, I hope they will improve some of the visual elements (battery icons, or stock app icon...) ;)

Nevertheless, changes are significant, even bigger than in macOS Yosemite.
