E-paper is making strides and has lead to a screen that is the width of 3 hairs. Flexible and bendable screens are needed to replace printed things. I seriously can't wait to be able to pick up a piece of E-paper and read the news and stuff. It should be disposable as well.

The material, only as thick as three human hairs, displays black text on a whitish-gray background with a resolution similar to that of a typical laptop computer screen.
