You don't really have to learn how to use all the bells and whistles for it to be effective and ideal. Heck, I use it because it saves me having to transfers files or allows me to develop on a separate box through ssh if I don't feel like setting up expand drive or the likes.

Also, hjkl is the most beautiful thing I've ever experienced, I constantly wish TextMate and VisualStudio gave me the separation from edit/navigate mode like VIM does.
