The Rough Guide to iPods, iTunes & Music Online by Peter Buckley and Duncan Clark Rough Guides $70 The iPod became ubiquitous so quickly that it's embarrassing to admit you don't know your way around the weighty little slab of hard disk. Enter Rough Guides, specialists in making us instant experts in everything from The Da Vinci Code to the music of Zimbabwe. Buckley and Clark explain the legalities of downloading music, the quality of the sound, how to manage files and the best online music services. Tech snobs may also pick up tips on using the iPod to transport documents, backing up your photo archive and holding your Mac's recovery software in case it crashes. I now know how to turn the iPod into a musical alarm clock or a voice recorder. But I remain clueless about why iPod has the infuriating habit of alphabetising every album's track-list.
