There's an interesting debate taking place about the merits and virtues of modern electronic books like Apple's iBooks or Amazon's Kindle books and their traditional counterparts -- old fashioned paper bound and proper.
They're qualitatively different, inarguably. The feel of board and cloth and leather is warm and textured compared to the crisp coolness of glass, aluminum, and plastic. The gentle sound of pages flipping is vastly different than a tap or swipe or click. The sharp smell of a fresh new novel or musky scent of an old tome exists in a different dimension from the relative sterility of chips and displays.
Yet the weight, permanence, and nostalgia of traditional books can be a disadvantage when it comes to
carrying them, correcting them, and moving the state of the art of knowledge forward once again.
