There is a Swedish MP3 player that is a very good one.
JOS MP100 128MB or 256Mb
Built in FM radio, just put the player in one USB-port and your OS will find the player. No extra software needed. Just copy your MP3s to the device.
I have not got mine yet...but I have friends who have the 128Mb version...and it is very good. I like it because it also works like an USB-memory stick.
