I still don't get how one is supposed to easily get docs to and from this machine. It's billed as a distraction-free writing device, but if you're supposed to quit the program, stick in a thumb drive, issue commands to mount it, copy the files from some unknown location, dismount, and return to the program, then it's a pretty distraction-full experience. There basically needs to be a single program (an "OS" in a sens…
Maybe you could have networking enabled, but only in the background and without any software at all that could distract, just a background service syncing files?
I used to have a laptop running FreeDOS for distraction free hobby programming. Used a USB floppy drive and moved files using floppies, which seemed appropriate for a DOS laptop, but was not very convenient. If I set something like that up again I would probably use Linux or some BSD instead, with network in the background somehow. (But possibly DOSBox or QEMU+FreeDOS for the user interface to be less distracting).
