It was a shame Sony never produced a consumer grade minidisc writer for PCs. I always wanted to be as cool as Neo in the original Matrix, sharing warez on minidiscs.
They also made some later Vaios with MD drives built-in but I don't believe those could handle data, just music.
It's also always struck me as one of those products that was primarily made for the japanese market and they didn't really care as much about the rest of the world, it was a walkman 2.0 thing for japan since they fucking love walkman.
