You sound a lot like my colleagues when I tell them why I much favor dynamic languages like Ruby and Python over Java. :) They listen politely to my arguments, then shrug their shoulders and go "meh, Java works fine for me". CVS users are the same when it comes to Subversion users who are the same when it comes to Git users.

It doesn't matter for a "works fine" person how many faults their current tool has or how much smoother "your" tool solves all those problems, they won't listen. Logic doesn't work maybe because it is very hard for them to get used to something new. Maybe because if you haven't experienced any alternatives it is very hard to imagine that something could be better.
