I'm not very sympathetic towards the rental of DRM-locked text books. It just seems wrong. Yes, I understand it takes money and effort to write and compile a book, but since currently the prices of ebooks are way too high (after all print, shipping and retail are mostly left out) I feel that the publishing industry is moving towards what the music industry is today.

Everyone that has specialized knowledge, enthusiasts, professionals, professors etc. should write their own books and articles and sell them cheaply or give them out for free. Cut out the middle-man that is a publishing company. They are no, longer, needed. They just aren't.
