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.
So, I am now a longtime emacs (and evil, love vim-ey things) user, and I've dipped my toes in the org-mode water a few times, but it's never quite stuck.
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.
(People keep telling me I'd love emacs, and I have nothing against it, I just happened to learn vim first.)
