My tutorial for setting up fish on Mac OS X and Ubuntu: http://hackercodex.com/guide/install-fish-shell-mac-ubuntu/

I've never had any trouble using chsh to make fish the default shell. Bash scripts in crontabs still run under bash -- not sure why anyone would think otherwise. Plus, changing the shell command for iTerm/Terminal won't help with remote servers, so using chsh everywhere means you always get a consistent shell experience, no matter whether you're using your terminal locally or remotely.
