Agreed. I had a photography teacher in high school who used to say that photography was 50% science and 50% art — that you needed to master the technical stuff (chemical temperatures, film speeds, aperture size / shutter speed etc.) in order to be able to forget it and concentrate on the art. Apple has worked hard to shorten the initial learning curve on most of their products — osx the iphone, the ipod all tend to be easier to learn initially than comparative products.
That’s pretty much why most artists I know (and I’m one of them) like to use them. It has nothing to do with their technical power. In fact, I think most artists wouldn’t disagree that Windows machines, for instance, are probably more powerful and ultimately able to do more than Mac. But apple computers are very easy to use, and allow you (with some major exceptions) to do what you want on them — whether it’s edit photos, or record music, or make movies. So you can get through the technical stuff a little faster, and get to the art — the stuff that most artists are more interested in.
I personally like mac machines and I recommend them to friends. I don’t think much about what it “says” about me. If there were a cheaper PC that was as easy to figure out, as free from hassles, viruses, spyware, adware, and crap, and had all the software I wanted, I’d use it.
