I've written three novels (unplublished) in text editors, including Vim but never Nano, and on all sorts of devices from PalmPilots to phones to tablets, laptops and desktops running all major operating systems. I'm doing editing of one novel in Obsidian right now. I try to stay away from word processors until the very latest stage, because everyone I know who would critique or edit only use Word. For linear fiction, which uses only parts, chapters and scenes, Markdown works just fine and Pandoc works really well for converting to other formats.
