Isn't it because the quipment is so expensive we have to complain on CD costs ? Can spend it only once.
For me the problem is that the record company complain about the fact copying is done so much their market is collapsing. As a reaction they raise the price. A general raise of price i can understand: inflation, but its a technology where you would expect that larger numbers mean lower cost per item. I do not see that back.
I also buy DVD's more easy than CD's. A DVD offers perhaps more value to me for the money, as you get satisfaction for both ears and eyes. Once you get used to more input you might prefer/expect that. And so the CD becomes lesser value, and seems expensive in comparisation to a DVD.
