I've thought about Apple graphics and CPU performance for some time and have reached this conclusion: Apple does not make leading edge, state of the art computers. Apple makes extremely well thought out, beautiful and beautifully functioning computers. It's all about balance - literally and figuratively.
Anyone who bemoans Apple's lack of fast graphics cards does not understand what I think Apple's goals are in the laptop market. I really don't believe they care about top level performance. They seem to want something that works well and that meshes with their design concerns (power, size, heat etc). They also don't ever seem to be in a hurry. There is no rush on their part to update a line just because some new faster chip or card has been released. In the movie "Objectified" a designer speaks about how they look not at the specific needs of the demographic the client company is targeting, but rather at the extremes of those needs. If they can make the product meet the needs of the top and bottom, the middle will take care of itself. I'm not so sure Apple does that. I think their products are in fact aimed at the middle and purposely leave out the top and bottom demands of consumer needs. Certainly when it comes to technical performance anyway. I'm not sure I can remember when a Mac was clearly at the utmost top end of technical performance. There always seems to be a PC out there somewhere that dramatically exceeds Apple's offerings.
So don't et your hopes up about the new MBPs and their graphics. I bet they will be squarely in the middle.
