Every Windows 10 PC can have Hololens

Now calling it 'mixed reality', makes some sense, distinguishing the terms augmented versus virtual reality has sometimes been difficult, but trying to push another term is confusing too.  Mixed means what?  Recently saw a Hololens demo at a Microsoft store and it was impressive.  But will this be a break in the use of augmented reality by consumers, by the enterprise?   Beyond gaming.  Still no clear golden application.  And its still expensive.
