There are no in-depth explanations about networking, no UNIX commands or how to hack the system, and no detailed descriptions of how it all works and why. In short, it's not a "tell me all about it" book - it's a "here's how to do it" book, and that's why it works so amazingly well. Plus, if you look up how to do a particular task, and Mac OS X offers new features, new shortcuts, or new options that weren't available in Mac OS 8/9 (and there are plenty in Panther), Scott includes those too, using the same right to the point, conversational writing style that made his "Mac OS X Killer Tips" book a smash bestseller! We can't imagine an easier, faster, or more fun way to convert to Mac OS X, and really start using it today.
