They're way too expensive especially on bigger sizes. I want one as my second monitor but I won't be able to get one soon.

By the way, you can still create a distraction-free environment for yourself with GUI. Just go with a minimal setup, something like Niri, Sway, river etc. (Openbox, bspwm, i3wm, Xmonad, dwm if you prefer X11).

The key points for distraction-free is to have a minimal desktop and using a program launcher like d-menu, fuzzel or rofi. TUI programs also help a lot. This way you won't need a second OS setup and can do everything in the same installation because TTY is restrictive for certain things.

There are also distraction-free GUI programs that you can use. For example I prefer ghostwriter as my go-to markdown editor, Apostrophe is also great if you prefer GTK. Depending on your use cases, there are a lot of programs like these.
