Apple is interesting. They certainly have the money and I think the idea of fabricating their own chips appeals to Apple, but at then end of the day I don't really think it makes sense. Apple won't want to fab for others or design chips for others.

The only way it happens is if it is kept separate kind of like the Beats acquisition. Apple lends some chip designs to Intel and Apple starts fabricating their chips on Intel fabs, but otherwise the companies operate independently.
