ironically as little as ten years ago college kids were playing cds on mini systems...which soundwise were superior to most pc based computer speaker systems of today...and the industry has always predicted every 20 years or so a new medium will emerge..and the ipod/itunes did just that...it wont take another 20 for downloads to dominate...the decline of the cd AND dvd has already been implemented...they wont become relics overnight..but close enough for confusion
