The problem for me, is that so long as there is DRM attached, I don't feel like I've purchased something I own. Therefore, that erodes significantly the price I am willing to pay for Kindle ebooks; I enjoy reading on the Kindle more, so I like having the ebook, but I don't want to spend money to be locked-in. My threshold right now for an ebook is at least a 40% discount relative to the price I could purchase the physical book, to offset the DRM risk.
Ideally, what I would like would be to be able to buy a paper book, and get the ebook bundled for $X more (say, $2-$5 more). I would have the satisfaction of a book on the shelf, actually owning the book, and then the convenience of an ebook. I would also be less bothered by the presence of DRM. If I could buy DRM-free ebooks from Amazon, I would be willing to pay closer to price parity of the corresponding paper book.
