The RIO Cubic (Carbon C)
The Rio Carbon was an extremely anticipated audio player that never made it to market. Like the other Rio players it had FLAC,OGG, MP3, WMA support and a 30GB HD with 30 hours of battery life. A former employee of Rio has provided Engadget pictures of the now defunct Rio Carbon along with the Carbon manual. The Engadget article has more pictures in one article than all the previous articles combined. RIP Carbon.
