Welcome, the Flexi-Disc Tablet!
A company called Plastic Logic have come up with a tablet that looks like a Flexi-Disc, or, as they prefer, "looks and feels just like a sheet of paper".
Basically, it is a 10.7in touchscreen device, designed to be used a few at a time, with different apps or windows running on each PaperTab, each aware of each other. Have a look.
As you can see, the flexibility of the device is a key part of the interface. Bending the page helps you scroll and navigate. And it is all backed by second-gen Intel Core i5 processors.
However, if you're going to need multiple devices, this won't be taking down existing tablets any time soon, and could well be consigned to the Nice Idea skip, along with Flexi Discs.
