The reason OS X is not on other hardware is simple. Drivers. Apple does not want to have to worry about them or others writing drivers. Having it tied to their product is the easy way to put out an OS.
I've said for a long time that this obsession of Mr. Jobs in havng his hardware and software tightly-coupled is what hurts them so much.
But at this point if Mr. Jobs relents and lets OS-X run on anything else but Apple hardware people will hound him till his retirement with "I told you so".
He would have proven Devorak right, and that is just something Mr. Jobs cannot (emotionaly) do, is to admit someone else is right.
No, if Mr. Jobs was going to de-couple the hardware from the software then he would do it first on the iPod where there is no where near the emotional baggage. Has he done this? Can you use iTunes with some other media player?
Nope. (which means he will not learn the lesson)
