I've been using Macs for all kinds of stuff, since 1986, so I can definitely state they get work done.
But I still strongly believe that Apple hates pro users because they don't make as much money and because they get in the way of serving laymen. The Aperture fiasco, the Final Cut Saga, the Xcode war of attrition and the never ending chain of failures with MacPro - all suggest that I'm right.

As an Apple developer, since then, I have been incandescent with rage at Apple, many times.
Guess I’m a walking demonstration of Stockholm Syndrome (at least, that’s what I’ve been told).
