On October 23, 2001, Apple Computer, a company known for its chic, cutting-edge technology -- if not necessarily for its dominant market share -- launched a product with an enticing promise: You can carry an entire music collection in your pocket. It was called the iPod. What happened next exceeded the company's wildest dreams. Over 50 million people have inserted the device's distinctive white buds into their ears, and the iPod has become a global obsession. "The Perfect Thing" is the definitive account, from design and marketing to startling impact, of Apple's iPod, the signature device of our young century.Besides being one of the most successful consumer products in decades, the iPod has changed our behavior and even our society. It has transformed Apple from a computer company into a consumer electronics giant. It has remolded the music business, altering not only the means of distribution but even the ways in which people enjoy and think about music. Its ubiquity and its universally acknowledged coolness have made it a symbol for the digital age itself, with commentators remarking on "the iPod generation." Now the iPod is beginning to transform the broadcast industry, too, as podcasting becomes a way to access radio and television programming. Meanwhile millions of Podheads obsess about their gizmo, reveling in the personal soundtrack it offers them, basking in the social cachet it lends them, even wondering whether the device itself has its own musical preferences.Stev
