Jason Snell, Macworld:

Start by considering exactly what Federighi said on stage at WWDC: “We love the Mac, and we love macOS because it’s explicitly created to the unique ergonomics of Mac hardware, like the ergonomics of the keyboard and trackpad, the flexibility in displays and storage, and because of the power it exposes, it makes the Mac able to accomplish almost anything.”

And:

I’m not sure I can entirely conceive of iOS never having a tool like the Terminal—if only because it feels inevitable that app development will one day be possible on iOS—but I can accept that the wild-west feel of macOS, where you can arbitrarily install, compile, and write software, is unlikely to ever be reflected on iOS.

And:

Apple itself sells a keyboard for the iPad Pro, and even allows users to move their fingers like they’re using a trackpad when editing text. The iPhone and iMac Pro are about as far as two devices can get from one another, but the MacBook and the iPad Pro are not.

To me, there’s still a huge chasm between any Mac and any iOS device. The Mac was built to serve a cursor, a specific location on the screen that has a focus. There are windows that you can drag around, a file system designed for rapid file/folder moves and copies, searches and sorts.

On the flip side, iOS devices are built for the dynamic nature of touch. All areas of the screen are equal citizens when it comes to touch. There’s no nudging things to the side without specifically reaching for them. No arrow keys to move a text cursor back and forth, or move an object from side to side.

Though I do see Jason’s point, the differences between a MacBook and a keyboard enabled iPad Pro are less than that of the iPhone and iMac Pro, to me they are still worlds apart.

All that said, Jason’t article is a terrific read, worth your time, thoughtful as always. I look forward to next year’s WWDC when we see a truly informed Marzipan, when Apple delivers a framework specifically designed to bridge the macOS iOS chasm.
