For years, I have "compiled stuff by hand" of OS X - not a bad approach, but it takes time. If I was just a software developer I would probably run OS X most of the time because I would have my tools built and installed once and no repeat time wasting work. For me, I also write on tech a lot, and sometimes I get some consulting work fitting people's projects to technology stacks. As a result, I have the perfect excuse to try just about everything and installing "everything" is simpler on Linux.

If Homebrew develops into a great system in the future, I might boot less to Ubuntu.
