I find it absolutely distressing that it looks like the minidisc format is going the way of the buggywhip. I am; I'm 60 & having used practically format since the casette for Music on the go- I think the Minidisc-hands down- is the best format ever. Without rehashing all the virtues of each format Mp3 etc etc-suffice it to that Minidisc gives me the listener the best bang for the buck in terms of fidelity, portability, and control of what I want to listen to. I dropped my Sony mz-si at work. It hit the floor in such a way that it works no more so a 910 will be at my door when I get home from work. So much for shock proof. In any case-There are probably a myriad of reasons why this format is not more popular. But the reason I see as it is really irritating and annoying-was (is) Sony's preoccupation with "ilegal" downloading and DRM. They are really quite stupid, ignorant, and arrogant. In my situation 98% of what I listen to I paid for (CD purchase) and were it not for the fact I like this format-I would have told them to shove it with my wallet
