What convinced me to give Obsidian a twirl is that there's essentially no danger of sunk costs: I already store my notes as markdown files in a local folder synced via cloud service between browsers and mobile, and accessed via IDEs/plaintext editors. Obsidian merely replaces the IDE as an access/manipulation point.
The only 'cost', so to speak, is adding bidirectional link syntax, which I suspect is soon to become a common standard. I am curious to see what happens when they open up their developer API, as the Obsidian PKM community is quite active.
