Better yet, pick up a Kobo. You drop a zip file on the SD card and get a full Linux environment.
I picked up a few of them for $10 each (used)
Care to tell more about what you did with yours and where to start if you‘d want to install a Linux environment? Sounds like a great idea since these precious e-ink screens shouldn’t end up on a landfill yet!
do you have any links on how to do it/what models should we look to get for doing this?
