Note I intentionally avoided any specific software. This concept involves producing hardware only, to be purchased in single samples or in bulk by a software/service company and resold with modular components (storage, battery, etc) and software added.

A quick explanation on the sketch: when closed, the screen is facing the keyboard and protected from scratches. To open, you fold it like a laptop. Once open, you can slide it up/down over the keyboard like the N810 and N900. I'm aware of the usability flaw of having "bumps" on the left/right edges-- though I don't know a good solution to it as of yet.

Finally, any ideas on how one might convince some company to build it? :P
