The first big update to iTunes added MP3 CD burning, an equalizer, and cross fading to Apple's music player. But its most important feature was being able to sync with an iPod—the cool new MP3 player that Apple had just released. By simply plugging it in, iTunes could sync songs and playlists with the device, and you could carry around "1,000 songs in your pocket," as Steve Jobs famously said during the unveiling of the iPod.

In the next decade, computers moved from being our primary way of surfing the Internet to acting as a storage center for the data on our music players, phones, and tablets.
