What are the current market options for e-ink /displays/devices that you could program on/ that you know of and (don't?) recommend ?

I got a Boox note air 2. It's an e-ink device/android tablet/e-reader/note-taking.

You can install any app on this device. I find it's acceptable to code with web-ides like replit.com. But my main usage is reading and note taking.

Is the notable delay between keyboard sounds and video rendering due to the SSH/software?

Later he writes a comment saying is due to network latency. Seems a bit dubious if you ask me though.

Seems legit to me.

Using an Onyx BOOX with Termux, terminal lag is not perceptible. The lagged updates look like packet jitter to me.

Could be the classic nagle / delayed ack interaction. Or shoddy wifi.

An interesting test case would be the aalib demo, bb:

Here videoed off an emissive display: https://yewtu.be/watch?v=WubDqdV2r9k

And what seems to be a direct screen capture: https://yewtu.be/watch?v=JFFJYJ6QkME

I'm also curious as to what display damage high-speed refresh causes, and what reasonable guidelines at avoiding this might be. I have an Onyx BOOX Max Lumi, whose display is excellent, and do very occasionally watch video. (More often I'll simply play the audio via mpv in Termux.)

Imagine where electronic ink displays could be today if E Ink wasn't such a terrible steward of the initial technology.

I'd say you might get your wish in about five years, after present patents expire. There will doubtless be new developments, but present devices are absolutely sufficient for e-book reading and most web surfing / tablet tasks, even at monochrome and modest 0.5 -- 16 Hz refresh or so. Higher-quality display is slower to refresh, though almost all instances are well under sub-second.

Colour displays are slower as I understand.

I personally use a Remarkable 1 with yaft (1) as a terminal. I connect via ssh to a tmux session for editing and the response is fast enough.

There is the PineNote [1], don't have one but do have the equivalent SBC.

This is great, looks totally usable.

I've pursued that eInk life style for about a decade now :) My best setup is with a Dasung Paperlike, but in practice the ergonomics keeps me from using it often (too many things to carry outside and setup). What I hope to see one day is a Linux friendly laptop with an eInk display (frontlit for extra bonus [1]). I wouldn't use it as a replacement, but for quickly grabbing when spending a few hours outside. Maybe Framework or MNT Reform could do it?

[1] the Dasung has multiple settings for the backlight and it's an absolute necessity for using it indoors.

EDIT: backlit -> frontlit, silly me.

ADD: PineNote is also promising as it support BLE and thus could be used with remote keyboard/mouse.
