Since people seem interested, I'm just interested in the idea of making a dedicated, distraction-free writing board that would be a standalone system. Hook the TKL keyboard internals directly to the Raspberry Pi, then have the screen boot directly into FocusWriter. If I was able to power it with a usb battery pack, i think it could be a fun project... though I'm just casually researching at the moment. I haven't taken any serious steps toward starting the build yet.
