Having re-transitioned last year back to the land of Free *nixen after a long stint on OS X, I marvel at how awesome package management is, and wonder how I ever gave it up. Even where I'm now forced to use OS X (work), I try to brew / brew cask everything.

The Windows / Mac distribution model feels more like a necessity on a closed system than something that is ideal.

EDIT: I realize that comment sounds more critical than what I intended. While I have a preference for package management, others clearly don't. Also, I might be inclined to use something like this for fast-moving big apps where I want the newest features. I could see trying Guile-Emacs or QGIS this way.
