Its not the idea of paying that bothers me so much as the price point. I know damn well there's nowhere near the overhead costs to digital distribution that there are to printing, publishing and retail, why am I only getting a $5.00 discount? Popular digital books and MP3 albums could cost $2 and still be profitable...
Not to mention that I can't resell or exchange the digital copies like I could physical media, so there's no longterm value. If you consume as much media as I do you'll quickly go broke if you were to pay what they wanted, and not be able to at least recoup some of the value in tradeins.
$9.00+ for digital DRMed media is a total ripoff.
