I believe that if a business can use some legacy win apps without booting several OS's that would be beneficial for Apple, it would allow for a migration without the pain of app retraining, and since it renowned for a more secure environment, and its apps are exceptional. For education, this could be the turnaround for Mac OS to counter any perceived hardware cost impost. I agree that it may have to be an arms length venture.
I dont think businesses (large installs) would be favourably receptive to a multi OS machine - its too much of an admin headache, its for the very few or developers.
