The publishers are going to go through the same process the music industry went through for 7-10 years and hopefully we'll eventually have DRM free books. The difference between books and music is that while someone might want to listen to a particular song out of their thousand song library at any given time, it's much more unlikely that someone would like that kind of random access to their books. I just hope DRM will only be an annoyance and won't sabotage eBook reader adoption.
