IMHO the best way of reducing ebook prices in the long term would be to buy as many and as pricy books as possible. The publishing houses will not be enthusiastic participants in the ebook revolution if they are constantly nagged by stingy ebook customers arguing that an ebook is something less than a paper book and should therefore subsequently cost less.
Prices will not go down before the marked mechanisms dictate them to do so. And these mechanisms will not come into play before the ebook business gain some momentum and volume.
Given the current and future cost of the liseuses, such volume will not come from the cost-conscious who uses the e-book as a cheap substitute for paper, but from people who have realized (as we all have
) that e is superior to p - no matter the cost.
