Panasonic released two digital audio players for consumer markets. These players make a difference to regular players, because they use AAC format instead of MP3 -- AAC is part of MPEG2 standard and can produce much smaller files than MP3 with better sound quality (MP3 is part of MPEG1 standard (MPEG-1 audio layer III = MP3)).
Problem with the player is price -- over $400 for a player that uses Panasonic's own memory card standard (=expensive extra memory).
