@leo wide angle lenses are a bit of an obscure taste. even photographers don't love them. very silly people (like me) do, and that's knowing that they effectively need post-processing.

i might accept two transflective lcd screens with a more traditional laptop hinge, in some A6 or A7 shape, because that basically emulates a book and we could do it with some reliability.

the usefulness is obscure though, as most people no longer read and very few people outside of college both read and pocket annotate, so for the most part i would probably rather just have the phone keyboard back on a slide or a gimbal
