alt Hacker NewsPerhaps a stupid question, But I always thought the whole point of e-ink displays was to have non-volatile display, that is, a mostly static display that persists when the power is out. These projects that focus on driving them at high speed, Is there any actual advantage in using e-ink tech at that point?

Great readability in direct sunlight without needing to compensate with a powerful front/backlight is one good argument.
Reading a book on e-paper in daylight is so much nicer than on a phone, for example.

Is also "reflective" (natural) vs "emitting" (a compromise idea that worked but should not have you take it for granted - we do not "read fire" in nature).

They claim e-paper doesn't rape your eyes due to it being passive.
It's a niche use, but if backlit screens trigger migraines (as they do for mine), then high-speed e-ink is almost a pre-requisite for using traditional interactive UI. At ~15fps typing is OK but using a mouse cursor sucks. Outdoor use is a bonus. RLCD is another option.
