Well, that's fine if it's true. If it makes my next Mac even lighter, or have a longer battery life, that's a good reason to do it. Honestly, I don't care what ISA is used, and most people probably won't. Everything on the Mac app store will port over pretty easily, so doing this will be even easier than it was in 2005. All of the software I write nowadays is portable, so I don't care even from that perspective (Python, Ruby and Javascript, etc. run on anything). For me, this is about as much of a non-event as a switch to a different GPU or RAM supplier.

As long as the XCode toolchain exists on such devices (ie, they are full dev devices), I would be more than thrilled to switch architectures with a new MacbookARM.
