I think Apple slowly is trying to merge iOS and OS/X, and then it will happen.
After all of the tech blogs screamed about hating OSs “designed for touch”, and not wanting all of that app junk on a real computer.
Apple themselves had said they think the idea of a touch OS hybrid like Windows was a stupid idea.
Apple’s fans ran around for months mocking the Surface for every reason under the sun.
But in the usual fashion, Apple will now rush the same thing to the market, and all of their fans will say that Apple waited so that it can be “done right”.
Did Apple learn nothing from Windows 8?
Actually, now that I think about it, I don't see why Apple couldn't in the short-run make a MacBook Air Touch that just runs both OS's with a shared storage area for user files. Detach the keyboard and iOS loads automatically - reattach it and OS/X comes back. It might be slightly cumbersome in some ways, but I imagine such a device would still sell very well. I'd buy it. :)
