I guess I'm in the minority because if the book has decent illustrations or photos, I'd rather have it then a dvd or video. I can have it right at my fingertips to view and reference. Also, I can take it anywhere to read at anytime. A book cannot get scratched. I don't have to concern myself with dropping it. I don't need something to see it. The visualization won't get ruined with age. Besides, the books look good on a shelf.
