Ah Minidisc. I bought a Minidisc hifi and Walkman back in the 90s. I was convinced it was going to take off. Much better than CDs but I guess the ubiquity and lower cost of CDs won out. The Walkman got stolen in a burglary years ago but I had the hifi until recently when - perhaps ironically - the CD changer died on it and I put it out for kerbside collection. I hope somebody got some use out of it.
