TOOLS
I use PC at home and Mac at work,
Mac's are the most beautiful, sexy looking computers to grace this planet....they remind me of Pamela Anderson (no offense meant to her)...it is therefor amazing what some people are able to do with these machines, which makes me thing! Hmm, I wonder if they had an abacus and a couple of crayons, they could probably create art, regardless of the tool at hand. In other words, it isn't the tool that makes the art, it is the one using the tool, who does.
Comparing Apple with Windows and all its myriads of hard ware configurations isn't fair to apple, as they can only support a very limited different configurations, but what for what they are, pretty and slick, they do perform well, in skilled hands.
I myself choose not to use Apple for myself, with the exception of my iPod, another great design, slick looking. Though I have to confess, that there has been a time or two, when I have look to the other side, wonder what that beauty might do for me, but no thanks.
In my experience, I have more problems with the Macpro's that I am using, once the state of the arts (Dual Dualcore), so it is a few steps behind. However, when I compare it to my AMD Opteron Dual Dualcore, at the same clock rate, working on the same or similar images. It surprises me time and time again, that the Mac just doesn't get the job done that fast, despite it has almost twice the ram (Mac 14gb vs AMD 8gb (2005 vintage)) both have the same hard drives, both uses some kind of software raid, only the video card is different Mac with its default card and my PC with a Quadro FX3400, so there is a difference, but not major.
Anyway, if you want to use a Mac, by all means go ahead, as long as I can use what I wish to use, and should I one day choose differently, well great!
Enjoy photography and computing which ever way you choose to do it :-)
