I like E-Ink screens. Because they don't emit any light, they don't hurt my eyes or make me tired. I like their grainy, analogue look. I made this website so it would look OK on a black and white e-ink screen.
I have a Dasung Paperlike monitor. I just put it in front of my laptop screen with a rubber band to hold it. I make sure no light is seeping out from the laptop screen behind it!
There's e-ink tablets available, and some can show color. I heard they show muted pastel colors, which sounds nice.
You can get an e-ink phone too, and it has a qwerty keyboard with physical buttons! I like that.
