Well, that’s kinda stupid on their part, but I bet they will be rejoining AR race later though, probably too late while Apple and Google creates good AR platforms with massive support of 3rd parties. And I expect Google (or, ekhm, Alphabet?) to show something like that in next few years.

Still, as for Windows AR devices, I expect to there being some 3rd party ones in ~10 years, that have computing power of desktop PC’s we had yesterday or we have today. And we can already see that even mid-budget mobile devices can run heavy desktop environments (like Windows or some Linux desktops (like GNOME and KDE)) with no issues whatsoever, this is just going to expand into AR devices.
