On this day in 2001, Apple CEO Steve Jobs unveiled the original iPod. He began the presentation by teasing “a breakthrough digital device that’s not a Mac.” Ultimately, the iPod that was revealed that day became a pocket-sized digital music player phenomenon, and would be many gadget fans' favorite always-carry device before smartphones matured enough to make such things redundant. The key claim iPod launched with was that it could put your entire music library in your pocket for $399.
