When Steve Jobs introduced the iPhone in his January 9, 2007, keynote address, he called it “a widescreen iPod, mobile phone, and Internet communicator.” And it was. Later in the speech, he explained that it ran a version of Mac OS X, designed for “desktop-class applications.” And it did—but the iPhone only used the applications that Apple chose to build into its firmware. Developers could only write apps to run in the Web browser, or be installed on hacked, or jailbroken, iPhones.
The iPod is not only the best-looking and best-selling music player to date but also a springboard from which dozens of accessories have launched and soared. These products turn your iPod from a mere digital music player into multi-functional tool--that happens to play episodes of Family Guy. Some attachments are so useful that it makes you wonder why Apple didn’t think of it first. In fact, some of these accessories can become so integral to your iPod that it can feel naked without them.
