Looking at the price of eInk monitors, I've been tempted to try using a spare eReader as an external eInk monitor — or connect a USB keyboard, and run Linux on it.<p>Cursory research turns up projects such as KoboWriter (https://github.com/olup/kobowriter/) which seem to have overcome some of the difficulties (though the process is still involved).<p>Has anyone done something like this? If so, how did it go? (And where can I read about it!)
