Similar to my note setup with one change -- Vimwiki + Syncthing. I'm also using(abusing) git to daily auto-commit everything, so I could delete everything without worry, and browse history with tooling I'm already familiar with.
This setup works quite well across all the devices I use (desktop, laptop, phone). With a caveat that phone setup is mostly read-only (apart from ticking the grocery list on occasion) due to it being just a folder with text files there.
I'm actually curious to hear from other vim to emacs org-mode converts since the article didn't elaborate on the cons and pros of the switch. How significantly is org-mode better than vimwiki and is it worth exploring for someone who's been baking in vim ecosystem for a decade?
