However having used Xcode at some point 10 years ago my belief is that the app ecosystem exists in spite of that and that people would never choose this given the choice.

edit: I suppose I should also note the vast majority of people developing on mac books (in my experience anyway) are actually targeting chrome.

I work in video games, you know, industry larger than films - 10 out of 10 devs I know are on Windows. I have a work issued Mac just to do some iOS dev and I honestly don't understand how anyone can use it day to day as their main dev machine, it's just so restrictive in what the OS allows you to do.
