Walkman vs. the first iPod: your music collection moved inside the player
Sony’s 1979 Walkman carried a cassette. Apple’s 2001 iPod announcement promised up to 1,000 songs on a 5 GB hard drive.

The Walkman made the music portable. The iPod made choosing the next album portable, too. You could leave the bag of cassettes at home and carry the library inside the player.
| Original launch products | Sony TPS-L2 Walkman | First-generation iPod |
|---|---|---|
| Introduction | 1979 (Sony) | 2001 (Apple) |
| Music storage | Removable cassette (Sony) | 5 GB hard drive (Apple) |
| Library claim | Depends on the loaded cassette | Up to 1,000 songs (Apple) |
| Recording | Playback only (Sony) | Music loaded from a Mac (Apple) |
Sony’s history says people worried the Walkman would fail without recording. Cutting that function was part of the product that shipped. Apple’s launch announcement adds a different dependency: its new player syncs with iTunes on a Mac.
At the announced $399, dividing the first iPod’s price by its advertised 1,000-song capacity gives about 40 cents of player per stored song. That excludes buying the songs and the computer, and “up to” still applies. Compress longer songs differently and the count changes.
The next tradeoff is already visible in that library: once every album fits, choosing what to hear becomes the part the hardware cannot finish for you.
