What's Your Favorite iMac Tip?

http://live.pirillo.com - Yeah... I have a new iMac. Isn't she gorgeous? I've been looking at getting one for awhile, to use for a machine to live stream. The live stream has been being powered using a Mac Mini that's kind of old. It's just underpowered, and not easy to keep everything going. So anyway, the iMac is going to run the chat and stream, and hopefully everything will run much more smoothly.
