This looks spectacular for Emacs. I don't need more than 5fps.

  Framerate is one thing, but you should consider typing latency. At 5fps, you get an average of 200ms of extra latency from the display alone, on top of everything else (keyboard, OS, application, GPU, etc). https://aresluna.org/keyboard-secrets/typing-delay/ https://aresluna.org/keyboard-secrets/typing-delay/ EDIT: oh and remember, you're going to get an awful lot of perceptible jitter, depending on how close to the exact time of refresh you've hit the key.

    Just like back in the days you did server admin over dialup. I'd say vi is more suited to high latency though.

    E-ink is a bit funny with refresh rates. An entire display can take a long time but a character cell can actually be pretty quick, and they aren't tied to a clock rate. However, connecting it to Windows graphic drivers may make it hard to have that kind of incremental update.

      Indeed, which makes me hopeful it will at one point be viable to DIY a cheap, low-wattage computing/hacking device, based around an SBC or a beefy MCU. I haven't done a full sweep of the e-ink landscape in a while, but the consensus a couple years ago was that all the low-latency solutions are still on the expensive side (you're better off with a regular screen).
