Well looks like the Windows Phone Platform is dead and gone, which will please a number of clients I know who this year just rolled it out to their users.
What next, since now there are only two real players in the phone space, Android and iOS? If Microsoft want to control both hardware and software, like Apple do and Google do with their Pixel phones, well they can still do that (sort of) with Android? Samsung do it with Android, they take the stock Android OS and add their TouchWiz layer to it. A Microsoft version of Android? Could be nice with the new UI design they are rolling out to Win10.
Update: They are doing that… great minds uh!
