Interesting read on how Intel sees the myth (that ARM is more power efficient because of the instruction set, rather than the limited performance of the SOCs) http://www.extremetech.com/computin...s-no-future-for-arm-or-any-of-its-competitors Personally, I'm of the same opinion. Medfield is a nice proof of it all and Adnroid phones running x86 Medfield SoCs should provide ample proof of that. ARM is not more power efficient at the same performance levels. Apple is not going to suddenly do another architecture change for Mac users, there is no advantage to moving away from x86. I think a lot of the wishful thinking of ARM moving to x86 is a wish by people wanting to be "black sheeps" in computing. Not running the same architecture as the other guys are, being marginal. The clique that are "PowerPC fans!" aren't PPC fans because it's better, but because it's different. Difference for difference sake's is sad. Stop trying to define yourself based on goods. Again, my opinion on the whole thing.
