Most of my music collection has been encoded in OGG Vorbis because Oggs are patent-free, are smaller, and – most importantly – they sound better. I was thinking I was stuck with using my Zaurus PDA for taking my music with me, since there aren’t many portable Ogg players out there.
Then I found the iRiver, a 40GB portable player, with MP3 and Ogg support and an integrated FM transmitter.
Oh, and it runs Linux, too. Pretty cool.
