AFAIK no one's figured out how to get Linux on it yet, but the Daylight Computer otherwise fits that ticket for me. I have mine set up with a Bluetooth keyboard/mouse and a no-name tablet stand :)
The benefit I think people don't understand about these low-fi writing setups is that it's much harder to _idly goof off_. There are times where I truly want to read or write, but if I'm on a computer it's too easy for muscle memory to kick in and start typing one of many distracting URLs into the address bar. My tablet is a much more constrained experience, and the screen is monochrome; last time I sat down to write on it, I actually had Google Docs open for three or four hours straight.
That’s exactly my experience, albeit with a Supernote tablet instead. I wanted it specifically because it can’t do anything not related to me entering words into it.
