Yes, I'm well aware of the reasons why my computers get faster even at lower clock speeds. I think of the megahertz myth, I picture clock speeds staying the same and getting more done at those clock speeds (e.g., all my computers would forever be pegged at 2 GHz but would continue to get faster). It was only today that I realized that clock speeds (at least in my case) are going down (rather than staying constant) while computation ability and battery life continue to increase.
