“Hacking iPod + iTunes” (US$24.99) is the latest book from veteran Macintosh expert Scott Knaster. The title is filled with tips and tricks for using Apple’s iPod and reveals many little-known secrets about iTunes. “Some of the tweaks Knaster explains include how to download e-mail, news headlines, and driving directions to an iPod, view the songs on an iPod from the Finder without any additional software, and even how to fully replace the iPod main menu with your own.”
