Inventions: paper vs. flat-panel display

One of the greatest inventions ever is a simple piece of paper, fluttering in your hand as you carry your scribbled ideas from one room to another. Also impressive because of its technology and adaptibility is the flat-panel computer display which, while far more streamlined than its clunky cathode-ray-tube predecessor, appeals mainly for the same reason: the paper-thin page/blotter/palette that it projects electronically before our eyes. It also contains our words, our images, our plans and our dreams.
