i picked up a mz-n1 last year and after hearing about the new 1gb players, i was thinking about becoming a minidisc lifer - getting a hi-md home system, car player, portable stereo, etc. however, before taking the plunge, i want to know how long the portables last. i can't afford to lay out $2-300 every two years. i've noticed one member who has a list as long as my arm of devices he's used... i've got a portable cd player that's been through a fairly rough life that works beautifully and i want to know... is it worth it?
