I was really happy with my Droid purchase, and that was before I found out that the Droid plays .ogg files.
When I purchased my music player, I specifically bought one that supports ogg vorbis, the open music format. I ended up with a Cowon D2.
Just transferred my ogg files over to the Droid and they're playing now. Sweet. Out of the box Droid supports lots of music formats including ogg vorbis. Honestly, I'm impressed.
Way to go Verizon!
P.S. Anyone want to buy a used Cowon D2?
