For me, OS X has increasingly become too difficult for use in development. For a while there, it was the best, especially with tools like homebrew. But, it's just become too much of a headache. Too often, I find myself wasting hours trying to get over small OSS compatibility hurdles.<p>More and more, I've been finding myself picking up my 'other' laptop, firing up VirtualBox, and running Linux straight. I do miss the build quality of my MBP, though.
