I've been dreaming of an A4/letter sized e-ink device for some time. With a touch screen and notation capture (handwriting recognition would be pure gravy) it'd be a killer app for folks who handle a lot of PDF dox: lawyers (yeah, I know, but they have lots of money to spend), teachers, business persons, medical personnel ... the list goes on and on.
Think how many such devices would sell to a business environment! Yes, they'd be terribly expensive, but consider that businesses pay much more for stuff than typical individuals can/will -- where would the PC revolution be without businesses buying enough to bring the prices down where we could afford to have the things ourselves?
And the detail that it would be good for reading books fixed-formatted in that size is just an incidental detail.
I'm just all tingly merely
thinking about it.
