Along with Evil, Emacs org-mode is the thing that eventually lures a number of people like you over from Vim. Evil makes editing in Emacs close enough (very close) to editing in Vim. Org-mode gives useful functionality that you can't get in Vim.
Have you got any suggestions? The number of people that recommend it makes me sure that there's value to be had there, but it's never really become a habit for me.
