The thing is Win RT it's not anything like previous versions of Windows, both from a user interface standpoint and from API/ABI compatibility standpoint. it does not support Active Directory, fullnExchange or most other Microsoft enterprise integration tech. There is no compelling reason for a corporation to go with surface.

Bizarrely iOS and Android both have better Microsoft stack integration.
