Is a Courier-like device possible right now?

2 screens with a bezel of less than a centimeter, a sturdy hinge. The second screen to be used as a keyboard when neede. I don't know, but I think that would offer the biggest possible screen on a tablet (2x 7" for example), while also making it comfortable to hold. It could be used as a tablet, a "book" and a laptop.

What do you think, do you have any ideas?
