While that's true of OS X, it is not true of Darwin, AFAIK.  I believe  
you can run Darwin on pretty much any PC hardware.

It didn't work for Mac OS X's previous incarnation, though, in the  
form of NextSTEP, did it?  Selling that platform as an OS and  
abandoning hardware manufacture did not save NeXT.

And with open source operating systems not far behind in many  
respects, I don't know how much future there really is in basing a  
business on operating system software unless, as in Microsoft's case,  
you already have an effective monopoly.
