It’s not religion, but it is close. My attachment to vi has only grown since I first really gave it a shot little over two years ago. Getting vi keybindings in a Java editor pushed me to finally scrap Eclipse in favor of NetBeans.
At work I’m a little more heavily tied down in terms of IDEs. Ditching VisualStudio is not easy at $EMPLOYER. Imagine the joy I just experienced when I discovered VsVim. Happy days!
