[Not that I agree with software patents at all. I personally
don't
create MP3 files. If a decent portable/car player with OGG-vorbis
support shouw up I'll by one, but not until them. My only current use of
MPEG is DVD/DVB, where their is really no alternative (yet).]
From what I've heard the rio karma is ogg compatible and outputs
VERY
good sound quality.
