Are we moving towards a tablet-laptop hybrid Apple device in the next few years I wonder? (similar to MS Surface).. I know there's the issue of cannibalisation but I think such a device could be awesome (but hard to do right)
OSX is designed for a keyboard and mouse. iOS is designed for a finger.
They have wildly different semantics e.g. precision, gestures that you can't abstract without ending up with a horribly compromised experience e.g. Windows tablet mode. And that's just not in Apple's DNA.
That line has been becoming blurrier for years now. iPadOS supports keyboard and mouse inputs, and the UI is moving closer to replicating a desktop experience on every release. macOS has supported touch gestures for a long time, and the UI is moving closer to resembling a mobile experience.
It's not hard to imagine full convergence of both OSs and the devices that run them. As usual, Apple can claim to be the innovator in this change, even though competitors have been doing it, admittedly worse, much earlier.
But it might be the best effort yet of unifying mobile device and desktop experiences.
The industry just needs to keep trying is all. Eventually someone is going to get it right. It's anyone's game, and all the major players thus far have fucked it up multiple times.
