A new survey has been conducted by BookBoon on people's preferences between ebooks and printed textbooks in the school environment. Over 2,164 US students participated in the study, which gives us some solid information on the digital vs. print debate. Over 75% of US students regularly choose not to buy the textbooks their professors require, citing the huge expense involved. Statistically, on average they spend around $655 per year buying textbooks required for their studies.
