If this is true, I'm pretty interested to see how they intend to pull it off (and how it works out in real life). I'd be more skeptical if Apple hadn't already pulled off CPU architecture transitions with impressive smoothness multiple times already. Will Apple do an x64 CPU? Or maybe x64 emulation? ...maybe with custom hardware assist? Could they possibly do a crazy "you must recompile for ARM if you want to run on the latest Macs" thing? The performance of Apple's ARM CPUs is already fine for the lower end of lappys, and have superior power usage. Moving up into midrange performance lappys doesn't seem like a stretch at all to me, or even higher end lappys, especially if you're looking for more cores. But what about iMacm, iMac Pro and Mac Pro? Does Apple really have a solid plan that makes ARM CPUs competitive there? Or will there be Intel-based Macs at the high-end and ARM-based Macs at the mid to low end? Could Apple possibly tie all this to some unification of iOS and MacOS? And/or tie it to a unification of the iOS App Store and Mac App Store? Interesting stuff.
