Let me try to explain to you, with my best abilities, what you are missing.

You are missing nothing. Absolutely nothing. As a vim user.

org-mode, is a bunch of features, unrelated sometimes, put together in the emacs eco-system that work well together, and work well in the emacs eco-system.

Org (and sometimes, with extensions) can handle scheduling, task management, document production, journals, literate programming, writing html emails, maintaining contacts info, building knowledge base, writing blog articles, etc.

If you are a vim user, you probably better off sticking with markdown for creating documents, and then using pandoc to convert them. You are probably better off sticking with task warrior for tasks. You are probably better off sticking with a calendar app for schedule, ... you get the picture.

But in emacs, org-mode is integrated so well in the eco-system that it makes it quite powerful. You can, while reading some code, take a note immediately, pointing to the region (which includes a hyperlink to the line, as well as copy of the content of the highlighted region) and store it in your todo list, with a scheduled time to review. It will appear in your agenda when you ask emacs to view your agenda.

In emacs, you can write a document (in org-mode format) and then include it in an email (within emacs), which is automatically converted into html when you send (or text, or both MIME.), ... you probably get this picture too. Org-mode provides a set of APIs that allows for automation and customization.

Because emacs has many usecases, and because org-mode meets many of these usecases, and because it integrates well, org-mode has found a special place in the emacs community.
