Lots of people. This is great for office workers, because e-ink doesn’t cause eye strain like monitors do. And if all you’re doing is working with documents, this is a fantastic way to go.

I’d personally kill for a monitor like this because I work with text all day, every day.

Anybody who cares about their eyes?

I’m a graphic designer, and it could be interesting for working on CMYK files and actually see them as they would look on paper.

If it were more reasonably priced, I’d be excited to buy one. I sit in front of a screenful of code all day and it’s tiring on the eyes. Black-and-white e-ink is not as desirable because it’s helpful to have colourful syntax highlighting.

If the resolution is high enough, readers of comics, newspaper, magazines, textbooks, children’s books, maps, etc.
