Paper-like displays

The shrinking bulk of cellphones and digital organizers makes them easy to carry, but the miniaturization comes at a cost: the screens are shrinking along with the electronics. You can read a short text message on them, for instance, but not a page of a newspaper.

Within a year or two, however, you may be able to pull out a thin plastic screen from the side of your phone or digital organizer, read a magazine, a map, or a memo, then let the screen roll back into the device." http://www.nytimes.com/2005/03/17/technology/circuits/17next.html
