OK nobody's biting on this but in the meantime I got my 770 and gotta tell ya: this is a remarkable gizmo for $139 shipped! It includes WiFi and Bluetooth and an incredible screen, and when I set-up its Media Streamer to a simple uPnP server, I can start a song to play and add other songs & re-arrange etc. etc. Then while the thing is playing music, I can surf the Web and/or VNC into the other PCs on my network, and not skip a musical beat!

Very cool--highly recommended "Internet Tablet"!! If only it would listen to my Rio Central...
