And yet, the only thing you know about me is that I am not willing to grind my team of over ten programmers to a halt just to have them learn a tool (any tool, not just vi) that offers no quantifiable code quality or project-level productivity enhancements at all. By some accounts on other threads, mastering vim isn't a one-week stint, it could take weeks.
If you are saying that, in your own business you make decisions that would bring your entire team to almost an absolute without solid business or product quality justification. Well, more power to you. Live long and prosper.
