I've been getting used to OS X Panther for about a month now, making slow, incremental progress with my comfort level and efficiency. I picked up this book yesterday, and WOW, what a difference! In just 24 hours I feel like I'm some kind of power user -- all thanks to this book, which explains how to streamline and customize Panther with cool, focused tips and some well-chosen shareware apps. And it's such a good read -- I love Dr. Mac's clear and easygoing style! I especially like the "What Other Power Users Think You Should Know" chapter. Great stuff!
