I used Mercurial very briefly just to evaluate it; it's fine. I'm criticizing git. And i'm also saying DVCS in general is more complicated than the most typical use case of VCS.

Using Git for everything is like riding a bicycle with four derailleurs to pick up milk from the corner store. Granted, this is what I do right now; just because some technology is complicated or annoying doesn't mean I don't use it. But I wouldn't recommend it to others.
