E-Ink for productivity: Software and General Updates

There are certainly some e-ink devices that are able to do this, the TechnologyConnections fellow did a couple of videos that cover it, amongst other things: [link] & [this video] Though he is using a Boox product and I'm wary of them over the GPL violation thing: as well as the general “they'd piss & moan and send the lawyers round if someone took their stuff and used it unlicensed” hypocrisy, the paranoid cynic in me thinks there is something they want to hide in their customisations (hooks for calling home or some such). Also, those clips are a few years old now so some of the problems he was having may have been ironed out in newer devices & software updates. Another option is running a VMC client on any tablet that isn't walled off so that you can't: there are a number of VNC servers that create a hidden virtual screen and mirror that so the connecting client because the extra screen.
