I was just looking at getting a portable MP3 player and I noticed the Rio Nitrus. I've never heard of it before. It looks sharp. Anybody here know anything about it? Dell has it for $280 but it's only 1.5 GB while the Nomad Jukebox is only $300 and it's got 30 GB. Does the Nitrus make up for it in other ways or is it just overpriced?
