I think since apple is looking at the lower-end consumer market, it must also be looking at the corporate desktop market. Supporting enterprise software/fleet is a whole different ballgame. But it does play well into apple's strength, in that apple is great at letting others experiment and learn lessons from their failures.
If the new leadership at apples even glances in that direction, it will be wild for the desktop computing industry in general. Perhaps microsoft will rethink things, but better yet, entire companies and governments might start switching to MacOS.
Linux desktop is not ready for mass adaption, but it isn't that far off either. My opinion is that people using more macs get them more familiar with the unixy way of doing things. But better yet, a lot of the tooling and libraries for macs is easier to port to linux than from windows. macs dominating enterprise and consumer markets can mean improvements in linux desktop, and the eventual reality (perhaps in a decade) of seeing GNU/Linux desktops in those same spaces as viable options (Android/Linux is already there in the lowest of the low markets).
