I want one computing device, or an iPhone that can run OSX (or some future OS thats a blended version of IOS and OSX). Like a Switch that I can take me, or plug in at home and get more power/features.
The average user could no doubt make due with a minimal multi-window iOS interface. I have no idea how people work with an iPad in any serious capacity when you are restricted to a full screen interface.
"From mobile... to desktop. Yes, it’s the full Ubuntu desktop OS used by millions on a daily basis -- and it runs directly from the phone, so you’ll be able to move seamlessly from one environment to the other with no file syncing or transfers required. The core OS and applications are fully integrated with their smartphone equivalents, so you can even make and receive calls from the desktop while you work."
The more interesting thing is how tightly connected the macOS VM could be with the iOS VM (I use the term VM here loosly, they could easily be containers living side-by-side and not within a literal hypervisor).
For example, are there two processes running 'Mail' and two copies of every message so that iOS and macOS Mail apps are both working? Do I have to configure them both separately to connect to my accounts? That would be quite silly.
If you can get the two OSs sharing resources but still effectively providing desktop sized vs phone sized user interfaces that could be something quite powerful.
This already sort of happens with some web apps.
