While I have the utmost respect for my friend Charlie, this is one case where I respectfully disagree with his predictions.

Charlie's reports aside, Apple will not switch their laptops to ARM any time soon. Despite Apple’s previous migrations, there are too many technical and business challenges and too few benefits. Moreover, Apple's chip designers are better suited to enhancing the iPhone and iPad to fend off commodity Android systems. We look at the reasons Apple will stay with x86 notebooks for now, and how they might consider using ARM in the future.
