I loved Minidisc, especially the last-generation Hi-MD recorders. My MZ-DH10P with its color screen and (crappy but usable) built-in camera was, IMO, the coolest bit of technology I ever had in my hand at the time. But SonicStage was absolute garbage software. The last release freed up a little bit of the DRM restrictions (getting rid of the three-transfer rule), but it was still clunky and behind the times. Once I bought an iPhone, I had no reason to carry around a separate media player any more, nor any type of physical media.
RIP Minidisc. For this avid collector, you will always be missed.
