You can already get e-paper notepads that come close to replicating the feel of writing on dead trees, but E Ink thinks it can do better. The company has unveiled a new film, JustWrite, that promises more natural scribbling. It doesn't require a backlight or another display layer, and there's "almost no" lag. You won't have to strain your eyes or second-guess your drawing. The technology is also bendable, works with virtually any size and shape, and needs just a basic stylus as well as some basic electronics -- it shouldn't carry a significant premium.
