6 visions for your future computer

Imagine rolling your computer up like a blueprint and carrying it yoga-mat-style.

Meet the Rolltop, a laptop made out of a flexible display touchscreen that's are designed to be folded up, rolled around a cylindrical tube and carried over the shoulder. You can use it bent in half like a laptop, with a virtual keyboard appearing on the lower half, or you can flatten it like a giant tablet, writing on it with a built-in pen.

Since there's no actual prototype yet, it's impossible to speculate on when it would be available, or how much it could cost. The Rolltop is "buzzware": Its creators, the German design firm Orkin Design, built a splashy website to tout the concept and are looking for partners to make it a mass-market reality.
