Personally, I think that git is hard to learn if you try to think of it in terms of your previous VCS. As you say, you have a lot of svn experience, so maybe that's the issue.

Really, at its core, git is incredibly simple. That's one of the reasons that it's hard. It's just a DAG of changesets, and every command lets you manipulate that graph, or give points on the graph names.

Anyway, I'd echo several people's sentiments here: http://progit.org is a really good explanation, and also fairly short.
