Sort of. .Net is a strange one and creeps in as being located in the oddest of places. To be honest the company who is probably the most concerned is Adobe.
What a string of activities by Microsoft point to is a company that is embracing being at the centre of an ecosystem where Microsoft continues "to create a family of devices and services for individuals and businesses that empower people around the globe at home, at work and on the go, for the activities they value most". For Microsoft it isn't about quick wins and it never has been, it is about banking on the continued - - remember this is the company that made its breakthrough by selling an operating system on the IBM-PC on volume rather than machine: showing more confidence that people would buy the device than anybody else at the time imagined.
Remember the idea of “a computer on every desk and in every home” was for many years the mantra of Microsoft and did they move mountains in the pursuit of that goal and accomplish it to a far greater degree than anybody imaged. Now they want to put a computer on every person and in every business and they want that computer to be a Microsoft computer. If you connect computing peripherals - running Android for example - or connect to servers running any one of a dozen operating systems (frequently hosted on a Hyper-V platform)
I finally got an Android device a few weeks back (thanks MyBB) and it is lovely - I use it all the time for Skype (Microsoft) and Onedrive (Microsoft)
I haven't played with Remote Desktop yet but the point is my Android tablet is a peripheral that happens to also be my phone. The swing towards MS for people's smartphone is happening and will continue to happen. You can completely avoid the Apple ecosystem or the Google ecosystem but not the Microsoft one and that is what they want.
