Facinating post.
I thought that the key issue with running OSX on a PC is that the underlying 'kernel' of Mac Processor is Linux...unlike PCs which still run on Good Old DOS. So it's a matter of overall efficiency and crash mitigation. For those that wonder why Mac's don't licence the OS out, you must herken back a few years ago to when they actually did! Do you not remember the Mac Clones?
The concept caught on like wild fire but 'changed' the concept of a turnkey work environment. I doubt Apple will licence thier IP out like that ever again.
In all the CBA's I've done, Apple has consistently out preformed PC for Graphics, Multimedia and User-centric applications.
I doubt that situation has changed.
Also- keep in mind that Microsoft owns some Apple stock. after all, they do the R&D for MS

Soon the transition from MS think to Apple-think will accelerate and as volume accelerates, hopefully Apply prices will drop.
