I use WIndows at work by necessity and a Mac at home by choice. I've been a Mac user since long before iPod and iPhone etc. brought so many PC users over to the Mac side. There is much less disdain for Macs these days on the part of the Windows crowd, and Apple's mass-market success with the "i" products and their online music and app stores have a lot to do with that.

As far as Poser, I have not experienced the video-related problems reported by PC users, though the general bugs and design flaws are just as frustrating for both sides. For either PC or Mac, you need loads of RAM and the more processors the better.

The biggest drawback for Mac users (and not only for Poser) is so many vendors of software, utilities and scripts make their products for PC only. But this is getting better as more Windows users, including developers, expand their horizons. Netherworks, for example, has started making their python-driven products for both PCs and Macs.
