Who would buy a Mac when you could just install OS X on a PC? (Note: I don't necessarily subscribe to this viewpoint, but I think Apple do, and have historically. And I speak as someone who was cheap enough to buy a Mac Mini and bring my own monitor - the only way I could justifiably afford OS X)

That's the thing, Apple fans will just keep buying Apple no matter what. Even if you could by a PC with OS X there would always be a demand for Apple hardware. If Apple sold OS X separately from Macs people would still buy Macs.

Legally, you still would have to, yes.
