On the note of terminal displays, I've been looking for a good e-Ink tablet that runs either Ubuntu Linux, or Android with access to the Play Store, and has a decent enough refresh rate so I could run an ssh client and code on it from time to time with a Bluetooth keyboard for eye strain relief, and for coding outdoors in full sun.
I have a couple of ideas:
A large e-Ink display connected to a Raspberry Pi
A Boox tablet
Are there any others I should consider for this use case? My biggest concern is refresh rate. I usually edit with vim. Greyscale syntax highlighting would be a plus.
