Not really. The insertion point doesn't float. You can move it, but only within the text. Once it is placed in position, it is active. A cursor is different. It's floating on top of everything, waiting for a click to activate it. Clicking a button does one thing. Clicking within a text area does another. Etc.
I see it differently. If anything, I see support for a mouse, not a trackpad. When you're talking about "pro" users, they all use mice. I work with several architects. No one designs buildings with a trackpad. I have several photographer and videographer friends. Again, no one uses a trackpad.
That said, I think Apple would rather sell you BOTH an iPhone and a Mac, not an iPhone (or iPad) that turns into a quasi-Mac when you connect it to an external display. If you look back at Apple's history, they've almost always resisted the hardware "dock" idea (the problematic DuoDock being the exception). I really think their mouse replacement is already here. The Pencil. It's just as precise as a mouse and more precise than a trackpad. Adding a few tap and swipe gestures will let it do everything a mouse can do.
I agree that Apple wants to lock its customers in, but the iPad has a LONG way to go before it will remotely satisfy the needs of "pro" users. I think Apple is happy to move casual users to the iPad for a number of reasons, not the least of which is support. It's a lot harder for an inexperienced user to screw up an iPad (and wind up at the Genius Bar) than it is for him/her to screw up a Mac. Casual users are the low hanging fruit. It would take Apple many years to add all of the features necessary to satisfy the “pro” crowd.
I also agree that Apple wants to migrate the bulk (I will say ALL) of its users to a closed/controlled system. That's why I think they're moving the Mac more towards iOS, not making the iPad more Mac-like. Look at what they are doing to macOS and Mac hardware. Sandboxing. T2 security features. Restricting applications from unknown developers. Etc. And now we have Marzipan, which will allow iOS apps to come to the Mac. In time, though, this technology will mature and facilitate the creation of apps that can run on both touch and mouse-driven systems.
I think Apple will move the Mac to iOS one day and that variant of iOS will have a cursor, a menu bar, support multiple windows, etc. But it will also be very locked down, probably won't provide direct access to the filesystem, will only support apps from the App Store, etc. I don’t think we’ll ever see macOS on ARM. I think Apple is working on a new iOS-based desktop OS that will run on ARM-based “Macs” one day.
All fair points. I do think macOS will come to ARM though, only because we are reaching a tipping point in regards to performance. The power per watt reasoning Apple used to transition to Intel is even more so apparent today. By 2020, it will look pretty dumb if they aren’t taking advantage of the power of Apple’s chips. I agree with the locked down part though and the shared app platform that will drive iOS apps to the Mac and Mac apps to iOS. In the end, I’m happy using the iPad Pro as my main computer and see a ton of room for growth.
