For me, the following things stand out:
- Use your iPad as second screen for your Mac.
- Controller Support
- Use your X-box or PlayStation controller with your Apple tv.
- View your upcoming agenda items on the homescreen of your car.
- iPad OS
- iPad gets it’s own OS.
- iTunes break-up
- iTunes (on macOS) will be broken up into dedicated apps.
- Apple Sign-in
- Login with Apple, they can even create a “fake” email-address for you that automatically forwards!
