Mac is kind of not there in the developer community, unless you're talking about shops that deal primarily in the iOS space.

One of my coworkers was given a Mac laptop by IT, not sure why. He uses it to RDP into his Windows desktop. I've told him he should probably... fix that, but he says he's happy with his workflow, and who am I to judge. It's also helped us catch at least one RDP related bug in our software, which is nice.

Apple is rightfully very targeted towards the content creation crowd. It's a very spendy bread and butter to carry around in your pocket.
