Why not just Power Saver mode?

Putting your laptop in Power Saver mode is way more effective than using a tool like this. Was the Power Saver mode somehow not good enough? If you're on battery and not in Power Saver mode, shutting off Aero won't help that much (keeping the external LCD off would certainly help) compared to bumping the CPU down a notch or two.

I think that one of the main advantages is that this program enables you to automatically switch between power profiles depending on whether or not the laptop is on battery power.  On mine, it's configured to automatically switch to power saver when I unplug the computer.
