I am currently having the same issue trying to figure out which one is better. However this is my second semester in nursing school. Last semester I bought the physical textbooks. It was the worst decision I could have done. I am looking into e-books this semester and since it is going to be my first time I'm a little skeptical about it. The comments I have read so far have leaned more toward VitalSource. I'm still a little unsure; has anyone tried both interfaces? I would be accessing my books mostly on my tablet which is a samsung galaxy tab 3; has anyone used this and experienced any issues?
