If you like little pie charts that show you how much disk space is being taken up and green bars to show you how much memory you are using, install it. You might get some oohs and ahhs from technically illiterate people, but then when they are gone and it takes you 10 seconds to open notepad on your ghz machine, (6 of which are to scan the .txt file for some virus that is only theoretical) or crash guard "helpfully" rearranges your registry, youll regret it. Ok this is an exaggeration, but essentially the answer is that it is not worth the loss of resources for the gain you get. There are some nice utilities on it, and if you install it with only manual antivirus checks, and minimal system monitoring, it would probably be worth it.
