It's totally worth taking the time to sync your dotfiles via git. There's a little bit of maintenance involved whenever you make a config change on one system that you want to propagate elsewhere, but it pays off.

Personally, I just `git init && git remote add ...` in my home directory and have a .gitignore that ignores everything by default, so I have to `git add -f` whenever I want to sync a config. Submodules work well for `.vim/bundle/the-plugin`. It's also nice for syncing important zsh customizations like this one: https://github.com/MatrixManAtYrService/home2/blob/master/.z...
