SoCs, ARM especially, are the future I don't doubt. I am thankful Apple is pushing the industry to advance. But :-) until these kind of battery advancements trickle down to Linux and Windows, I really don't care to be in Apple Prison(TM) as a trade-off.

Also, Apple has a long and storied history of specification marketing hyperbole, so I am extremely skeptical these chips will get 'real-world' 2x battery life.

I will keep building my cased x86 behemoths and refurbished Thinkpads as long as there is stock available :-) Hmm, where did that rotary phone go...
