With both Mac and now Windows supporting these mobile-forced-to-desktop apps, I worry a bit about the poor UIs in our future.
On the one hand, maybe tablets will improve a bit because mobile apps will have even more incentive to spruce up their large-screen experiences.
On the other hand, literally every app I have seen auto-ported to desktop in this way has been awkward at best. Usually at least a few standard platform things just don’t work, like universal keyboard navigation. Having mobile UIs appear unaltered on the desktop is just jarring, at the very least requiring unnecessary scrolling and controls that do not resemble anything else.
And I am not convinced that this will improve with time; on the Mac side some of these pseudo-apps have had years to get better but they are still packed full of UI quirks.
