O’Reilly Media has published its latest “iPod: The Missing Manual” — now in its sixth edition (US$19.95 cover price). “Not only are there new iPods, there are very different iPods, at that. For example, the nano can now do video,” observes author J.D. Biersdorfer. “By the end of my book, readers will understand how the iPod works, not only for playing music and video, but all the other things it can do, like storing phone numbers or keeping your mind working with a few rounds of iQuiz.” David Pogue, the founder of the Missing Manual series and New York Times technology columnist, also contributed to the new iPod book.
