This is a concept laptop that is up for an award this week in competition, a design contest sponsored by Fujitsu.
If you took an ordinary laptop and chopped the keyboard and screen half then you'd have something like the Flexbook. The keyboard folds in half and then the screen closes around the keyboard.
You can also swivel the screen around and lay it flat on the keyboard. This next sketch might help you understand what it can do:
I love the design. the screen is exceptionally wide, but I can live with that.
Do you know what? This reminds me of the new Polymer Vision Readius. It's not quite the same device, but the Readius does have a similar type of screen.
