My parents got me one in 1999 after years of me asking. It was such a disappointment when mp3 players like iRiver came out soon after (that should have a page on the graveyard) and then iPod came out. The iRiver and similar product used flash memory too.
Also I disagree with the minidisc distribution being an issue. They were less popular but, in the U.K. at least, album releases in minidisc format were available in supermarkets as well as music and electronic retailers.
