I'm debating between this gen. or last gen. MBP for purchase, but this isn't about purchasing advice! I've looked everywhere, and see a lot of speculation, not not many definite answers, minus the NVIDIA site that says a big fat "no". However, I don't know if that's because of hardware or software ,and if Snow Leopard will change that. In short, will Snow Leopard make use of having TWO GPUs? Or is the point of having two, solely for battery life?
