I have complaints about the UI changes in OS X sometimes but it's still not as bad as half the Linux applications I'd use in place of OS X ones like Tower
And every time I try Linux i still have issues like the "sleep of death" and NVIDIA Optimus support being in poorly documented limbo (your dedicated GPU is both in use and out of use until you run a graphical benchmark and measure the current draw of your laptop)
And I prefer Homebrew to apt. I've never had Homebrew fail to install other packages because I had a package install break previously, which is always something that drove me nuts about apt.
