Rolltop: The Laptop that runs

Rolltop design concept is a German, nay a fantasy of a truly portable computer and sexy.

With a flexible 13-inch OLED display, this lovely toy-mail goes as puff pastry.

Then you plug the roll on the sector, the screen and keys light up.

You can even use it as a 17-inch touch pad with a stylus.
