The Kindle display can do latencies of <100ms if they're set to plain black and white --- the really slow refreshes are due to hacking it to make it do greyscale. I think that's comparable to the old greenscreen monitors, but I can't find any hard figures. Would certainly be worth a try. What I would really like, however, is a monitor-sized Sharp Memory LCD display, as made famous by the Pebble. The colour displays are things of beauty. The colour gamut's not brilliant, but they refresh instantly, consume practically no power, and look great. With the backlight turned off, you get an interesting metallic sheen that looks like no other display on earth. Even the monochrome ones are really cool. I have a development kit where the display can show white and silver --- like, metallic, reflective silver, which you can (just about) see your face in. Alas, they don't make them much bigger than watch sized.
