> But ... Apple isn't going to suddenly vanish. It would be a slow fade, and there's plenty of room for different things to happen. All those Mac users aren't going to be in a hurry to run to Windows. It's certainly possible Microsoft could build something attractive to them, but I think it's also quite possible that someone else could too.
I think it would take quite a significant investment — as much or more than e.g. Framework has sunk into building their hardware business — to smooth the desktop Linux experience out enough to appeal to non-developer Mac users. That last "10%" that the desktop Linux is missing is hard. It'd also probably take a unprecedented level of cooperation from hardware component manufacturers to make high quality Linux drivers available for components from day one (the general consumer isn't going to want to wait somewhere between half and a full generation for robust hardware support, as is the case with the components in many prebuilt computers).
That's not impossible but it'd take a confluence of events that I don't see as particularly likely.
> …wouldn't an MS world be better? I am certainly no fan of Windows, but it does seem much more compatible, and usable in broader ecosystems than Macs do.
Compatibility and flexibility are qualities Windows has now at least in part due to meaningful competition. Make no mistake, Microsoft would love to command a walled garden of their own if they could, and in the absence of Macs they could probably boil the frog into making such a thing reality.
