Disagree
None of the Windows Phones or other devices will run desktop software at all, so I'm not sure what you are referring to. It isn't going to be any easier to use Windows-based tablets, etc. than Apple- or Droid-based devices, and given which of those have the higher market share, it's not hard to tell which is in higher demand (hint: NOT Microsoft).
We'll see what happens, but Microsoft really has a long ways to go to catch up in the mobile devices market and this new desktop OS isn't helping.
