The Music Match program (included) or some sort of plugin could include a little easier way to keep track of which MP3 file is where.
Another down... the lithium ion battery is permanently installed so you can't replace it.. (take good care of it)
This little player is really neat. I bought this thing because I wanted an MP3 play, and I got the bonus of being able to use it as disk drive as well.
Comes with everything you need (including a nice case)!
The only dissappointment I have is that 40MB is the limit for a disk. Basically that means you can put about an album on a disk at at CD quality. You can go down in quality to store more but I tried the 64 bit rate and you get that ringing sound in the music like listening online through a 56k modem!
