I would be so incredibly sad if paper books went away. I love, love, love the look of my bookshelf. All the different spines, every single one cracked and bent and loved, with the familiar titles staring back at me.
A digital screen with a list just doesn't do it for me. I know that the digital will take over, and that's fine with me. Maybe my leatherbound volumes will be as cheap as VHS someday :)
