E-paper moved a little to the background since tablets stormed the market but the technology still holds a lot of promise for the future. Over at CES 2013, Plastic Logic showed off a 10.7" tablet concept built around a flexible, e-paper touchscreen. Created in cooperation with Intel and Queen's University, the prototype plugs into an Intel Core i5 "Sandy Bridge" based PC as it does not yet have a dedicated processor.
The prototype runs a Sandy Bridge-era Core i5 processor that lets it stand on its own, but it's ultimately designed to work as part of a team: position awareness lets multiple PaperTabs join together to share a work area, and tapping one tablet with content can send it to a waiting document in another. The bendy nature isn't just for durability and a paper-like feel, either, as readers can flip through pages just by bending the relevant side.
