Indeed. I think the inevitable discussion about best distro, which always comes up in this context, is more hurtful than constructive, since it may end up confusing and scaring away potential Windows-defectors.

The point is to get them to try out linux and get a taste for it, and only when they have become comfortable with the concept and realised it is not so scary of a change that some people claim, should they begin to consider which distro is right for them.

I haven't seen anyone argue on the ruleset of DnD, so I'm disregarding that, but I agree with your point. Remember: Switcning distros is easy.
