I'm actually not very taken with oh-my-zsh. It seems to add a layer of complexity while not really adding anything you couldn't just paste into your .zshrc. If it eliminated tinkering overhead that would be one thing, but in my experience it just gave me a new layer of software that needed tinkering.

It's along similar lines to copying someone else's rc file willy hilly, without understanding what you're getting. Extra layer of quirks and features that you need to figure out, on top of the already existing layer.
