Another one bites the dust! Sad, because I currently have 3 MD decks and 4 portables. I use the decks all the time. House with main system, basement with minimalist system, garage (great for the garage), well, you get the idea.
Used to record my sons band concerts and solo's at contest. They were great. Still are for live-location recording IMHO. True, they were introduced to replace the cassette, but they are so handy and don't degrade the sound like MP3's do that I guess I've got a soft spot for them.
I record my sax practice and am very happy with the MiniDisc.
I never got on the MP3 bandwagon due to the very lossy nature of them. I've used open reel since I was a kid in the 60's and still love MiniDisc for their ease and good quality.
