it has potential to replace MD's, and to make MP3 players REALLY shine..
I mean, people like MD's, becuase they're small, and don't skip and have good quality.
people don't like small MP3 players becuase they don't store much (so you either need low quality music, or you have to spend $$ to make it acceptable), however they're TINY
People don't like CD/MP3 players becuase they're somewhat bulky, and are more susceptable to bumps etc then MP3 players.
this could be a happy medium in other words..
