RollTop is a pretty interesting notebook concept, that’s flexible and foldable, being able to turn into some sort of paper roll lookalike device. The concept packs a 17 inch flat screen OLED display, supporting multitouch and using an interface that resembles the user-friendliness of the iPhone. Here’s a video showing what the concept is all about:

What’s really interesting is that the notebook can be folded into a 13 inch tablet PC and this device is truly portable, as demonstrated by its hanging belt, allowing it to be carried more easily. Said belt will also be used to power Rolltop, another ingenious idea, saving the user extra space.

When folded, the device is as compact as a water carrier and you should know that it also comes with a full keyboard.
