I've freelanced at two different motion graphics companies over the last year who finally got fed up and dumped all their mac pros for better spec windows pcs (and this despite them all being apple fans in general, they just couldn't deal with the limited spec hardware/lack of upgradeability any more). That's the way it's going to go in more creative companies, especially ones that do video and animation, unless Apple pull their finger out soon...
