A few tips, hmm... * Download Growl. It supports Notification Center but also supports third party apps, so you'll get a notification for non-Mac App Store apps. * If you use Windows Live Messenger, you can either use Skype or Adium. Both are great. * Use the hot corners. They're rather handy. * If you get a mouse, make sure to turn on the right-click in settings. * The touchpad is cool because you can do a lot of stuff just using your fingers (view all your apps, show all windows, for example). Find out how to do it in Settings. * Learn about Bootcamp. You can install Windows and switch back and forth if you want. * To eject things just drag the icon on the Desktop to the trash. * Apps to consider: Unplugged, Battery Status * Download VLC Player. It's free and is way better than Quicktime. * Look through Settings to get a feel of where everything is. Also, Finder is your friend (the Smiley face in the Dock). Above all, just have fun :)
