Here's a iPad Pro running a macOS Desktop using Duet and a iPhone 6+ as trackpad. Just playing with it, it's feels pretty amazing how well this could work if it is turned into a polished Apple product. Just imagine working in macOS on a document, than detaching the iPad or iPhone and you can just continue working. Ok, maybe detaching the iPhone is a bit of a stretch but having an iPhone sized interactive touchpad with haptic feedback, 3D-touch, Pencil support and similar options as the new TouchBar is probably pretty cool. I can see why Apple decides to not unify macOS and iOS. Makes perfect sense. But integrating user experience at hardware level is a complete different thing. Apple is continuously integrating the macOS, iOS, watchOS and tvOS experience. The MacBook Pro shows that there is benefits in integrating these concepts in unique hardware. All it takes is a bit of courage If anyone feels like turning this into a Kickstarter project, I'm in!
