Found this awhile back at Sandbox Technologies.
Folio at SandboxTechnologies
Excerpt from site :- It provides similar functionality to that of other small PDAs like the 3Com PalmPilot. Unfolding the Foldable Computer once doubles its size, providing the ability to take notes and respond to email. Unfolding the computer a second time transforms it into a book form factor, suitable for web browsing and other electronic book documents. Completely unfolded, the display screen is 8.5" x 14", and suited for large, complex information. Moreover, at this size, the computer can be attached to a keyboard, powered from a wall outlet, and used like a traditional desktop computer.
