Book plug: iMovie HD 6 and iDVD 6 Visual QuickStart Guide
Jeff has posted the first chapter, for free, right here, aimed at helping you evaluate and purchase a digital camcorder. Jeff also maintains a blog that focuses on iMovie. (I relied on one of his excellent earlier books on iMovie to learn how to use that software -- the only editing package simple enough for even a journo to understand.) Kudos, Jeff! I'll buy you a cup of coffee next time I'm up in Seattle.
