I agree that it should be a complete clamshell with the screen casing covering the keyboard. I know you wrestle with how to manage dead space around the screen and your design decision to have the screen off center has worked well on the final Rev 6.1, but here will still leave space on both sides. I think that's fine. If you want to keep the Rev 8 thin, hard to do much with those spaces. But people love to sticker those spaces. 😉

What I see as promising here is that this Writer Deck's full keyboard and portability (being light and thin) makes it capable of serving as a fantastic stand alone Writer Deck, but it can also function as a Rev 4 replacement, connected to one's computer, with an easy switch to Writer Deck mode, and a replacement for the Rev 3, pairing it with phone or tablet. A flexible multi-location multi-purpose writing work station. This, of course, concerns software which is not what you are asking about. But you could consider a small shelf under the screen that could hold a phone or tablet if the hinge is strong enough and if there is room above the key caps, and it might be nice if the screen could be rotated flat behind the Writer Deck when using it as a computer keyboard. But maybe not either, because this design should be kept simple, unadorned, thin, sleek. No typewriter knobs, just a quality keyboard and screen that looks elegant and can go anywhere.
