What's interesting to me is that git does not seem like a "great dev tool" when you first start using it, especially if you're already used to another VCS. Right now I'm using SVN, Perforce and git for different projects and I definitely like git the most, but it took a while to get there. And it's not the centralized vs. decentralized per se, like 99.9% of git users I'm almost always within milliseconds of a central server. The big change was to treat my development "as-if" I was doing my own thing, decentralized, when in fact I'm not.
