Definitely. vim is hard to get used to, but after you do, it's damn powerful especially with plugins. Always nice to be able to do typing and coding entirely on the keyboard and not needing to move your hands to the mouse for something. Also, if you do any Linux cli stuff, you almost always have access to vi at LEAST. So being familiar with the tool she the gui and something like nano isn't available, is invaluable.
