I would LOVE to have this for working outdoors on a sunny day.
Here is a demo of the Pixel Qi10 display : https://www.youtube.com/watch?v=gi6DbFyZde8
They had a dual mode so you could have the look/feel of a normal backlight LCD panel but when you wanted to go outside you could toggle to transflective mode.
This means you would have normal refresh rates, color, multimedia, and an actual useful display when outdoors.
Not sure why they ever went bust or what happened to the IP for these displays.
Refresh rates on e-ink are more than sufficient for text, and suffice for getting a general sense of video, though I wouldn't call that a high-level experience.
Scrolling and similar are a bit rough, though the general solution is to avoid doing that, and instead navigate through pagination --- a full page (or portion) at a time.
Hard disagree but I understand this is personal and that perceived experience will vary across the board.
I agree that e-ink is great for _reading_ text which is why it is used in e-readers.
I'll say again that on the device I have, I can quite reasonably get a sense of a video.
Video of BOOX playing video: https://yewtu.be.com/watch?v=XRDJv_-wWBI (Videoception!) Yes, it's B&W, yes, the framerate is low (about 4--8 fps AFAICT), and yes, there's some ghosting. But it's clear what the content is. Not appreciably worth from an old B&W television in the day --- better resolution for lower framerate, perhaps, on e-ink.
If I'm writing text, it's almost always within vim or a similar text editor, and my navigation is either paging forward or back through the document (full-screen repaints), or using search. Again, that is well-suited to e-ink.
