At a previous company, I never told the new college grads that there were options other than vi, so unless they were enterprising enough to figure things alternatives by themselves (this was before widespread availability of Linux and the web), they were forced to learn it. And then I'd tell them about alternatives after they were proficient with vi. Not one ever switched away from vi. Did that cost us in initial productivity? Probably. But it's such a minor thing when it comes to NCGs.
