Rio recently introduced 7 new mp3 players, mostly tiny flash memory-based things. The most promising one is the Karma, which has a 20 GB hard drive and a 16 hour battery life. It includes a dock with RCA plugs and an ethernet port, so you can actually assign it an IP address and plug it into your network. It looks like a serious iPod contender. Pictures of the dock here and here, and a size comparison here.
