I've been using OS 9 for about a year, but when I upgraded to Apple's newest 10.2 (Jag) I felt like I was lost without a road map. I have this author's book on DVD recording and figured that he did a good job with Toast Titanium.
I can honestly say that after a solid weekend of using this 600+ page book, it has already paid for itself ten times over. It is really amazing how much gets covered. Networking and optimizing your desktop, all of Mail and the address book and all of the "i" programs are fully explained. I really like the fact that every single system Preferences option is discussed. He gives you clear information on what upgrades are out there, how to protect your system while you are on the net and how to make Jag run faster. Trouble shooting and QuickTime, remote control, Applescript and the unix terminal, and Classic mode are covered indepth too. Like other Dummies books you learn what to do, without the 'behind the curtain' tech stuff that you don't need.
I can't say enough about this book, except that the All-in-One part of the title is about as accurate as they come. If you need one reference book for your computer desk that will guide you through all of OS X Jag (and is still funny and an easy read), this great book is definitely it!
