Yeah, it sounds like they've put some time into it's development, which I suppose you'd have to for that sort of thing. He seemed to skirt around the questions regarding what sort of meaningful changes were put into the mac version (...um, it's prettier and the UI is less costumizable, but you have 2 color options?). And the guy who piped in at the end seemed a little overly defensive regarding autodesk's relationship with apple. It felt a bit like the guy being accused of being a racist who says, 'well, i've got a lot of black friends!' (or in this case we bought maya which is on the mac and there are lots of people here who have iphones).
All in all, I'd say that it's a good sign for mac users that they've created the mac version and I suspect it will work just as well as the windows version.
