that page lists a few devices they _don't_ recommend (kindle) because they are not openly hackable. what are some ones that are more so? anyone here recommend a cheap, hackable, e-ink reader?
Edit: I also experimented with the Poke 3 by creating a sort of "writerdeck" setup with a bluetooth keyboard and termux, then attaching everything together with velcro and magnets: https://chuck.is/writerdeck/
But kindle is The cheapest e-ink afaik
