Turning off wifi is probably just turning off your ability to do a lot of heavy processing as you interact with the internet, right?

This is my thought. Turn off wifi and you're no longer running the cpu and memory monster that is a web browser.

But this is something Apple does right. My wife noticed that she can get around 50% more battery life out of her Macbook using Safari instead of Firefox. (7-8 hours instead of 4-5).
