Pros
Pro Multiple Vaults
A Vault in Obsidian is like a database. Internal links and files are not shared across Vaults. Each Vault is opened with a separate instance of Obsidian. Each Vault can have its unique app settings and plug-ins. Useful if you have distinct/unrelated projects or "data spaces" requiring different workflows and data relations.
Pro Helps with planning and organization.
Variety of planning and organization plugins, such as Kanban boards or Day Planner.
Pro Incredible tool for PKM (Personal Knowledge Management) which allows anyone who has a computer and an internet connection to think better and create new insights
Pro Very easy to use and link notes, preserves the standard form of markdown
Linking notes is a game changing feature. Very easy to use and link notes. Their implementation of markdown doesn't deviate from the standard form of markdown and so the same files can be used by other markdown programs without any consequence.
Pro Multiple cursors
A feature unseen in other tools.
From the help doc, "This can be useful when modifying a lot of lines in the same way, for example putting - at the beginning of multiple lines to turn them into a list, or appending [[ to a series of links you’ve copied from elsewhere."
Pro Infinite panes, split panes, lock panes
In Obsidian, pane = window = note = page
Obsidian allows you to open as many notes as you can fit concurrently in your screen. You can split a pane horizontally/vertically. You can lock/link panes so they scroll in sync, useful for and edit & preview modes.
Cons
Con Proprietary software lock-in
Creates dependence on the application with the promise that the content is yours but that cannot be entirely true without the application being free and open source software. You will end up altering the way you create the content to take advantage of Obsidian features and your processes will evolve for its workflows. This replicates the lock-in pain that people experience moving their highly personal information from one proprietary platform to the next when that initial platform stops serving them well, goes out of business, or becomes a bad actor.
