I am interested in learning more about Leopard, but I am new to Mac and don't want a book that is hard to understand. Is this a good book? Your thoughts and recommendations.

I've heard great things about a book called "the missing manual."
Depends on your computer skill level. I have both the Peachpit book and Pogue's Missing Manual. The Peachpit is well written and very easy to understand. It doesn't go into details as fully as the Missing Manual. So if you are beginning in all things computers, I'd recommend Peachpit. If you're used to Windows and are new to Apple, the Missing Manual may be better. It covers subjects more fully, but expects you to know something about computers. Hope this helps,
