No, my argument was that there is parity between major OSes.
Again, and for reasons I have explained multiple times, Linux does not aggregate periods of CPU use/non-use because it has nothing like Grand Central, App-Nap & other technologies Apple has developed to get more efficient use of the hardware.
Again, OS X's advantage is trivially provable: Dual-boot Linux & OS X & see how long each OS lasts on battery performing the exact same tasks. Thousands of people have done so & the result is that OS X lasts in general 50% longer.
That's 50% more energy efficiency in OS X compared to Linux.
It's not a question of "you think that bla bla bla", it's been proven.
That your CPU spends part of it's time in low power states using Linux doesn't change the fact that it would spend 50% more time in low power states were you using OS X.
Just in case you're not to lazy or prejudiced to learn, here's a review of OS X that goes into some detail: http://arstechnica.com/apple/2.... It has graphics that even you should be able to understand.
