Neil Cybart, Above Avalon, in a post discussing Apple’s strategy on controlling sound:

The first iPod commercial highlighted the device’s mobility as the user danced around his house while listening to music via iPod and white earbuds. The kicker was found at the end as he stepped outside the four confined walls of his home and into the outside world without missing a beat. The iPod was about consuming sound not just around the home, but more importantly, outside the home.

Though the commercial is obviously dated (shown by aspect ratio, resolution, fashion, and tech), the sense of how deeply Apple gets music and its importance to people is clear.

Enjoy.
