My guess is the lack of software.I purchased a SCD-1 and after about a year sold it. One reason,lack of software.In the whole scheme of things,the choices still are pretty thin.Let's face it,the Bangles and Cyndi Lauper are pretty lame for a 5 grand player and overpriced cd's.Originally I thought the idea to be great,but as usual the music industry continues to shoot themselves in the foot.
