Rio has introduced the Rio Carbon - a replacement to their successful Rio Nitrus player. A 5Gb Hardrive based digital music player capable of playing mp3 as well as WMA. It has a battery life of 20 hours way longer than Apple's iPod mini of 8 hours.
The Carbon resembles the Nirtus in its design although the joy-stick has been replaced with a D-Pad. And gone is the black casing to be replaced with silver colour. If priced right this would be my next digital music portable player. Right now the only problem with it seems to be the lack of OggVorbis support.
