Coming from Windows, one thing I miss is the ability to control or select a power scheme for the CPU when it comes to throttling. i.e. right now I'm sitting on my bed watching MNF and doing some light surfing. I'd prefer if the 2.4ghz C2D in my MB clocked down to 1ghz or so since I'm not doing anything mildly intensive. However I've read that Macbooks run at full speed all the time even on battery which is bizarre. Is there anyway to configure it so that it's 100% full speed when plugged in and dynamic cpu speed on battery?!?! Seems odd can't do something this simple out of the box.
