Those don’t have physical keyboards, and all run Android which rules them out. I also prefer old school greyscale LCDs to e-ink, as e-ink has issues with ghosting and slow refresh.

The closest modern device is the Planet Computers PDA, which can run Linux, but it can’t run mainline Linux and it has a modern color screen that uses too much power.

I was going to mention Planet before I saw your follow-up comment. I bought their Gemini, and it seemed interesting for a while, but being a phone with a keyboard, still effectively a phone, battery life wasn't great and again a phone, my default was never to shut it down, and it would always be out of juice if not used for a while. Eventually it outdated itself sitting in a drawer; just didn't feel right. The external notification screen seemed like a good idea but too clunky for general use, and then the awkward fingerprint sensor position and accidentally touching things when opening / closing. I was actually considering it during my post-BlackBerry withdrawal period, but it just didn't cut it, and while it had the roots behind it and some seemingly nice productivity software, a Psion it just wasn't.
