Remember those antiquated days when students had to march around campus with 300 pounds worth of textbooks in their backpacks — those days are over thanks to VitalSource CourseSmart. CourseSmart is so easy, a freshman could do it. Students just search for the textbooks they need by name or ISBN and rent them at a discounted rate; the books are automatically added to their "bookshelf" to be accessed from a smartphone, laptop or tablet anytime, anywhere. Students can even print pages or take notes and highlight text. Now they just need to invent something that will do the coursework. Maybe someday.
