As a student once myself, I know how much to value the benefit of having access to my old school textbooks. I actually keep a few of them at my work place, where I can lookup important topics whenever I need to refresh my minds. So now publishers want to take this away from students by creating this b-i-z-a-r-r-e DRM scheme?
Based on what reasoning do electronic textbooks have to expire after a certain time?
