I keep hoping more book publishers will adopt Baen's (a big science fiction/fantasy publisher) approach. They release ARCs (Advance Reader Copies) in E-book form a couple months before the hardback book for $15. Then once the book is released, they sell it for a little under paperback price. The truly impressive part is this: There is ZERO DRM on their books. Not only is there no DRM, they let you re-download any of your books in any format you like indefinitely. They also have a free E-book library, where you can download many of their works completely free of charge. It's much more convenient, and higher-quality, than piracy. The end result is me spending more money on their books. When I drive to the bookstore, I usually can't find the book I want anyway - so I end up buying nothing. With Baen's system, I happily read the first book in a series free, then buy the rest of the series online. The other advantage to their approach is that since their costs are moderate, if I want to loan a book to a friend I'll occasionally buy the digital copy, then order a physical book to loan out!
