Early MP3 Players
The flash-memory bricks that freed your MP3s from the desktop. Diamond's Rio PMP300, arriving in September 1998 at $200, was the first MP3 player that actually caught on — deck-of-cards sized, running forever on one AA battery, holding maybe eight or ten songs. No moving parts meant no skips, a revelation after a decade of portable CD players. The RIAA sued to kill it; the courts sided with you instead.
