A few articles I found enlightening, with food-for-thought on what issues are important to consider in the potential (likely?) Mac move from Intel to ARM:
John Gruber takes apart Mark Gurman’s article (the Bloomberg piece that started off this wave), adding in his own thoughts on the question of emulation (see the Rosetta video at the end of this post), Book Camp and virtualization, and the impact this move might have on current Mac sales.
Next up is this TidBITS article from former long-time Apple Engineer David Shayer. A good backgrounder to read. Again, the question of a potential emulator rears its head. Will Windows emulation fall by the wayside in this new wave of Macs?
Last write-up is this piece from The Verge’s Dieter Bohn, What Windows can teach the Mac about the switch to ARM processors. Lots of detail on potential paths here. Will Windows emulation survive such a transition?
And, finally, here’s Steve Jobs, at WWDC 2005, announcing the Rosetta emulator, which translated PowerPC instructions to Intel x86 as the app was running. This was a critical step to moving the PowerPC universe to Intel. Jump to about 38:22 in for the start of that part of the video.
