At Robin Good you can see one of the first rollable displays.
"Rollable displays are projected to be the primary solution to the consequent demand for larger displays in mobile devices -- without increasing device size, weight, or power consumption.
The first likely entry in this arena is indeed a rollable black and white screen type which could be made be part of an existing cellphone, of a PDA/smartphone or could be used as an independent unit device.
Typical uses might likely be email reading, RSS feed browsing, and other text based applications which would not be handicapped by the lack of a color display."
