I think on a graphics oriented site like this you'll find a Lot of MacOS users (myself included).
This particular topic was really interesting since it really, in my view, outlines my biggest beef with the "Apple culture". That is, that they seem to believe that they are the center of computer innovation.
Object Desktop, for instance, originally came out for OS/2 in 1995. Yet somehow, features that we came up with are regularly claimed by Mac users to have been retroactively taken from the Mac. Whether that be our alpha blended shadows or zoomers or skinning.
As a Mac user myself, I use it for a great number of tasks. It has worked pretty well overall but like Windows, it is no where near perfect and get incensed when I see Mac fanatics come and act like MacOS X is nearly perfect and how terrible "Windoze" is (I'd put MS Movie Maker 2.0 against iMovie any day for instance).
