The unlearning point is definitely true. After using CVS for many years, Arch and then git were conceptually difficult to get into, and I was an early adopter of both. Not because they are actually difficult, but because your years of understanding of "how version control works" simply doesn't map onto the new way of doing things.

The last few weeks, after using git for a decade now I guess, I had to use CVS to checkout and contribute some changes to a project still using CVS. Wow, was that painful! One does get used to the simplicty and features of git, and going backward to older tools makes one really appreciate what they give you.
