I have read all of the back titles from Lee Child, purchased on my Kindle, but refuse to support the Greedy Publisher pricing and pay $13.95 for the latest Kindle preorder.
The Greedy Publishers are forgetting a key fact: Kindle purchases are basically read-once purchases, and that they can not be resold to the used marketplace. While I'm all for supporting the author, and have purchased more books in the last year (via kindle) than I have the previous five, that game is over.
A recent used book purchase ($0.15 for a slightly-used recent Michael Crichton) made me realize how Greedy and short-sighted the publishers are behaving. Well, good luck with that approach.
Meanwhile, I'll be supporting reasonably-priced Kindle titles and supporting recycled dead-tree books (where the publishers see no revenues).
