Have you written any kind of blog or documentation about the build? I've been interested in a mini-laptop e-ink solution for a while. I think that most of the coding I do takes very little resources and is primarily just talking to the cloud or other servers. No reason to lug around a bunch of resources I don't need, right?
I haven't, and I'm disappointed to see that the display I used is now discontinued. That will push me to use a more effective one in the next iteration, which I'll write up.
