Earlier quoted context omitted.
Let’s not pretend that Apple could come up with some sort of dual windowing system (or just dual boot) scheme. We’re not limited by drive space anymore. They don’t because it would hurt macbook sales.
Maybe they don't because they've seen what happens when Microsoft tried to build an OS that was both touch screen and mouse & keyboard.
The reason why it didn't work for microsoft is because adobe, valve, and aren't going to whatever framework just because microsoft wants them to. But in the linux world you can just fork and fix. Even apple has a lot of leverage to force developers to act in a certain way if they want that app store $$$.
Obviously the hardware isn't all there yet in the open source world (the pinephones are pretty underpowered), but in terms of software all of the right stuff is there. And don't tell me the UX is too complicated for new users. Gnome's design is literally a ripoff of MacOS and KDE's interface is pretty much Windows.
