I agree. Personally, I prefer getting used to the defaults than going through the pain of customization. I tried it, but it meant additional syncing between my machines, fighting with plugins, and it's not always possible to customize vi mode in some environments (like Eclipse or Sublime).

Overall, I think vim is great for simple and fast editing, but as soon as I need to work on a multiple files projects, I switch to something else, possibly using vi mode if there's one (and even there, I wonder if I shouldn't embrace mac os shortcuts once for all).
