Software theAppleBlog thinks you should use
The Apple Blog offers up some software that you should be using. While that seems a little aggressive to me there is some good software on their list. Amongst the suggestions are some familiar apps like coconutBattery (where have I read about that lately?), SCIT (sounds familiar), and some I have never heard of like FlashSaverMaker which turns any flash file into a screensaver.
Check out the whole list for some pretty cool apps.
