I am absolutely blown away at this. I will be shocked if Apple doesn't bring their processors to Mac within the next 5 years.
I know, right? Looking at the current Mac laptop line-up, the MacBook is now lighter, smaller and far less powerful than the MacBook Air (which is supposed to be the small, light, underpowered one). I think the MacBook is primed to become the first ARM Mac in the not too far future.
At this rate, they're going to get ahead of Intel. Not to mention, Apple is on a 7nm process while Intel's has been delayed for years now.
I believe Apple is treading carefully there, they need Intel in other areas still. They'd be careful not to cut them off unceremoniously.
