Devising custom word processor for custom device seems... overkill compared to cheap laptop with word processor installed (and nothing else) and in autostart...
Seasoned creatives I talk to find their environment and the feel of it very important to their productivity, and I think it's the same for computing.
When coding in Windows the feel is that of fluorescent lit room in 2005, sitting next to a filing cabinet with a Cisco phone on my desk that rings every 15 minutes.
Coding in my personalized linux setup makes me feel like a netrunner in cyberpunk and I love that. I know I can achieve the same work in Windows, but the vibes are different.
Absolutely my aesthetic, too. Sometimes, I'll spin up KDE just to get away from the terminals for a few hours, then back into i3/Sway.
