Maybe I'm going out on a limb here, but I think it is just a matter of time before apple drops intel. I say this for two reasons -
- Apple is all about vertical integration and supply chain management. Intel does not fit in this. As a matter of fact, as apple sells less traditional computers (laptops, desktops, workstations) and sell more post computer hardware (iPhones, iPads, etc), apples leverage with Intel will also diminish. Moving to a technology like ARM makes more sense. As they have done in with the iPhone and iPad, they control all aspects of the chip including release cycles.
- Moving to a common hardware platform, reduces cost in development. Although there are many components of iOS and OS X that are common, there is still a lot that has to be done to optimize for Intel versus the A series chips. Having a single platform should yield better code in that they only need to have one set of kernel code for a common hardware. There will still be difference at the UI layers to optimize for the form factor.
Again, I have no insight to what Tim and Jony are thinking, but this is how I read the tea leafs.
