Great coverage by macstories on the new iOS 6:
Seemingly foregoing power user-driven requests like better inter-app
communication and file sharing, Apple is focusing on polishing iOS as
we know it, adding subtle and more visible improvements without
drastically revolutionizing the experience we are accustomed to.
I think this summarizes why I have mixed feelings about iOS 6. I really
was hoping for better inter-app communication, improvements to
notification center and a more updated UI. I have no doubt that iOS 6 is
a big improvement (especially with Siri coming to iPad and Maps getting
overhauled), but I had my hopes up for a bit more.
