>carrying them in a backpack with a computer and notebooks can be a small but nice addition to the moderate exercise that is walking to me, heavy books aren't 'nice additions' but 'more strain to my back and neck' I actively did NOT enjoy slugging around my calculus books or actuarial mathematics books with me ... My kindle has made me read more. It also has reached it's 'break even' point in terms of value bought (10+ books read).
