My personal gripes: - updating the package index on each operation. I just want to install stuff, dammit. I don't need you to run git pull to update the gazillion package definitions - `brew update` and `brew upgrade` dichotomy. 99.9999999999% of the time I need to update/upgrade a package, not brew. If I ever needed to upgrade brew, I could run `brew update --brew` or something
