Well, Apple has obviously been doing well. iPod sales have been strong, and that's driving a new audience of people who have never owned Macs before. There was that existing audience of people who have always been Mac users, but now you're getting new Mac users too. At the same time, with the new Intel architecture, it's really easy to get that code over there. Plus, we use OpenGL, and Macs use OpenGL, so the rendering path was already there. We've been very pleased with the performance results on Mac.
