I agree with the eternal growth of HDD size but I'd like to ask you Taym if you are not using compressed zip files because now HDD drive are 40 GO ?

Yes maybe mp3 format will dissapear one day but there will always be such format with improved audio quality but not necessarly with file size reduction but audioi capacities nver equaled ..

I think DVD Audio could give impressive sensations like to be near a Philarmonic Orchestra in your Car ....
