The Flexbook was created by Taiwan-based designer Hao-Chun Huang for entry into Fujitsu’s 2011 Design Award contest. As the name implies, it’s basically a foldable netbook that can also be used as a tablet. The design is supposed to be waterproof, but only time will tell if this is possible in this form factor.
The Flexbook would have a 21:9 11-inch folding screen and is designed to be portable. My guess that it would use a flexible OLED screen of some kind. The keyboard could also fold up and can be deployed whenever needed. It would convert from netbook into a as tablet and e-book reader when the keyboard is stowed.
The design also calls for swappable rubber skins, which will allow for further customization.
It will be interesting to see what kinds of tablets, netbooks, and smartphones manufacturers come up with when flexible OLED screens become cheaply available. It’s safe to say that tablets, smarthphones and netbooks will probably end up being combined into one device once their displays can be folded.
