I was all in for Ubuntu on my home machines (Windows at work, of course), but OSX was a revelation. For core development stuff, Ubuntu is great-- I'm still a fan of Unity, apt-get, build-essential-- but as soon as I want/need to dabble in human-level tooling (basically anything with graphics), Linux falls down. The apps just aren't there, and if they are, they're not well maintained. Even the most actively developed Free apps just aren't as aesthetically pleasing in either the UI or in performance.

OSX makes me happy. The apps are considered and cared for by their makers, largely I believe, because they get paid for their time and ingenuity.

Libre works great for APIs, not so much for Ape-y eyes :).
