Emulating vi keybinding is great and all, but that only scratches the surface. A big reason people like vim is the extensibility. I don't think that there is a single vi user(not necessarily a power user, but someone who uses vim for more than just editing a value in a config file) who doesn't have a single plugin installed.

Great! Except you haven't told me anything about Vi(m) does that Netbeans, Eclipse or IDEA cannot do. We have powerful plugins too! I promise!
