To quote a reviewer: "We should not let the publishers hold us hostage because we prefer to read the electronic format.”

I think you're missing the principle matter: people are complaining that ebooks shouldn't cost as much as physical books because they cost less to produce. Nobody is saying they prefer physical books because they are physical objects, and nobody seems to be treating them like anything other than the same thing delivered in different ways at different costs. Find me evidence please that this whole thing isn't driven by the perception of fairness in what the product costs to produce.

Edit: Vote me down all you want, but lack of evidence is still lack of evidence. I guess when emotions run high people lose the need to make rational points and just downvote. Give me some justification. Argue with me.
