Here is an article about a new linux based AV stereo componenent

and it has a lot going for it: Plays your MP3s, MPEGs, VOBs, and soon Divx. Has standard audio and video ports, a sleek form factor, and what looks to be a sexxy interface. Its ethernet interface can take input from NFS or Samba, or the net. The only downside I see is that it has no DVD drive for built in ripping, and it has only a 20G drive. But at $400, this is pushing the line of reasonable for this type of device.
Should be available in Feb.
