Small suggestions for playing with it...
Im in loveeeeeee.
So who wants to show me all the little tid bits this OS can do haha
Several silly but clever tricks that impress people, two good apps, and some good things to know.
1)
Slow motion minimize -- Press the Shift key and press yellow minimize button on app window.
2)
Look at the UNIX underneath. -- It's a fun trick to show people.
This is only if you are very new to computers and won't be bored with command line. Change System Preferences > Accounts > account login options to show username and password. Note your account's "shortname", then logout of your Mac. At the login screen in the username field type:
>console and Click OK. You will be presented with the UNIX bash shell console login. Type your shortname/account name and password, pressing Enter after each. Don't worry, it is easy to get out of it. Type
cd / to navigate to your HD root. Type
ls -la to list all your folders and files. type
mkdir test! to make a directory/folder. Type
ls -la to list all folders and files, note your new test! folder. Type
logout to exit and return to your normal login. Delete the test! folder from your Macintosh HD.
3)
Make your Mac talk -- Open the Terminal app (Applications/Utilities) and type the command
say followed by a space and any phrase or sentence you want it to say. Example: say Hi there.
Apps
Good apps (other than the well known ones)
Photo Booth --kids really love it, and
Front Row
Huge Time Savers:
From any application, press the Command/

and the space bar at the same time to start a Spotlight search (upper right). This is the fastest way to find apps, documents, emails, web history, etc. Simply press Enter to open the top hit. Use arrow keys to navigate down. Learn that and you will look like a master.
In the same Spotlight field from above, type in a math formula (e.g., 12*27) to access the calculator function which displays the answer.
In the same Spotlight field from above, type in a word that is in the dictionary, press enter on that hit and the built in dictionary opens with that word.
Note that the Calendar app icon in the Dock always shows the actual date (new feature with Leopard). Set your clock to 11:59 PM to watch it switch over for "fun".
Misc.
Watch the videos here, they will teach you a lot, they are very well done:

Turn ON your
firewall (System Preferences > Security) Apple leaves it off by default. Why, I don't know.
Huge (but useful) Time Spenders:
Subscribe to
Mac related podcasts, The Mac Observer's Mac Geek Gab (the best), Twit's MacBreak Weekly, and the MacCast, all 3 are in iTunes. MacBreak Tech was a great one, but it is gone.
Great podcast if you like Steve Jobs
Search in iTunes for Apple Keynotes and subscribe to it. Go to your iTunes podcasts and "Get" the Macworld 2007 keynote. It is the one with the iPhone unveiling and he is at his best. It is fun to watch for anyone I think.
That would keep you busy for a day. Have fun. I'm sure there are much better things to do, but those are must knows and ideas for all I think. Enjoy your Mac. I am waiting on my first one ever, should be shipped any day. 24" 3.06 Ghz iMac with the now suspect ATI card.
