I get that, Floptical Drives were interestinf, but mp3 players and iPod didn't have great sound with the lossy format, and digital conversion.

I'm the type that hears the difference between lossy and something like WAV format. Lossy ones always sound muddy to me. So CD and DVD audio appeal to some people. And If I'm going to take a DAC with me, then a CD one is pretty neat.
