It's also better for your eyes, and does not require an electrical source. Also, in my own experience I tend to prefer hard copies.
Of course, I still use digital copies too. It just depend on price and whether I expect to use the book after I finish the class. E.g. Herpetology is probably not a subject I would study much later own, so I would just use a digital copy. However, I'm very interest in evolution, neuroscience, and genetics, so a book on one of those topic, I would probably purchase and continue reading later on.
