If you had told me ten years ago that it would be simpler and quicker to install any new open source tools/languages/frameworks on OSX than Linux, I would have laughed.
Yet here we are. Anything I need is a brew install away on my MacBook, but if I need to set it up in an Ubuntu environment, I need to figure out whether I can “just” apt-get it, or whether I need a custom ppa, or whether I need to get the .deb, or whether I just have to build from source.
I routinely notice this in the install instructions, where the OSX section is one-line, and the Linux section is split into Fedora, Arch, and maybe Ubuntu/Debian.
I know there are Good Reasons (tm) for this, but … it’s still surprising.
