These people have a somewhat modern alternative with mechanical keyboard and eink screen. It has wifi and that's it. From watching the reviews I understood that a major drawback is that no editing is possible on the device itself and it is very expensive (600$)

I personally use occasionally an android based ebook reader with a bluetooth keyboard (Onyx BOOX Poke 2 with logitech k380). Distraction free writing is a thing.
