I'm still a heavy vi user and I still continue to use vi for everything else, well except org-mode. 2 years ago, I did the jump and installed Emacs with Evil + Org-mode, i.e. I can use Emacs with vi commands. I use now org-mode daily - taking notes for my work, clocking in times, making at the end reports per project in order to make bills for my clients. I am far from using all org-mode functionalities, but already this improved the life for me sooo much - and I have all my vi keybindings. It goes so far, that make my programs to write reports in org-mode, so that I can read display, browse, search and drill down in them with org-mode - for big program generated reports it's a great advantage - they are nicely displayed, but at the same time you can use them with diffs (regression test reports), grep, etc. Additionally I use org-mode for project planning to generate gantt charts and as well for my private know-how database about IT matters - commands that I use, tricks, code snippets. This year I installed spacemacs, wich is an emacs with a special configuration, looks nicer and has the vi functionality built-in. That said, when I code, I use the terminal and vi.
