It's incredible how good of a design Vi is. Try this experiment: Busybox includes a tiny clone of vi with a reduced feature set. It's very stripped down when compared to Vim or even other vi clones, but as a pure text editor it's still more powerful than most modern day IDEs.
I love my Jetbrains IDEs, but you can take my Vim plugin from my cold dead hands :)
