I would get a MiniDisc over the Mp3 player for the following advantages/disadvantages
Advantage of MD
- 74Minutes of music per disc (disc are only US$1.5 each) you can start your 'collection' easily/swap with friends
- Sound Quality better than 128kbit MP3 for sure, I think you can compare MD to 160-192kbit/s AT LEAST
- Battery last a lot longer usually (my Kenwood Playback-only model last 50hours+ on 'bubblegum' and AA battery)
- Remote control are of better design (backlite LCD display is 'standard' to MD)
- Playback only model are really small and light already
Advantage of MP3
- 100% shockproof
- Smaller/Lighter than MD
Disadvantage of MD
- larger than MP3
- not as shockproof (but usually good enough - 40sec is standard)
Disadvantage of MP3
- Memory expensive as hell
- even with 64MB, only about 64minutes of audio at 128kbit/s
- shorter batter hours (i have seen some cheap one that last 8 hours)
- Sound quality worst than MD
- Remote control arent as good as MD
seems to me no Japanese based company are going for MP3 and they seems to be the best at innovation to me
by the way, i have just read that there is something called MDLP on a magazine
Mini Disc Long Play
it is a new MD standard which supports 2x*148 minutes) or 4x(296 minutes) the disc recording time in stereo format from a standard 74minute MD. For sure the quality is degraded but i think 2x is about quality of 128kbit MP3 and 4x is about 96 i think
the only company i see making MP3 are Diamond and Creative, along with some crappy korean companies
