Agree... NO! If Apple would do that the whole "Mac OS X consistency and stability" would come down in a second because they would have no control about the hardware you're running their OS on and all the pseudo-hackers out there would gladly download an illegal OSX copy just to figure out how to punch holes in it... it's would be a bad move all the way IMO.
You want OSX, save up and buy a Mac (like I did).
And the fact that Mac's are more expensive than PC's is a whole different thread, also discussed too many times, basically, you get what you pay for
