    Or do only the 9400/9600 get the acceleration?

    Not sure on that point, but something with the graphics drivers is new. My late 2007 macbook Pro's GUI transitions such as expose, the dock, minimization, and spaces seem to be really smooth. Stacks evens seem to be smoother. I also noticed the GPU and CPU not running quite as hot with this model (2.6ghz Santa Rosa), so my guess is there is something application/threading balancing magic going on.

    I could be wrong but I've heard that only the 9400 vid cards can do the h.264 acceleration. General usage though, I'm pretty sure that the 8600 can do general computing stuff when not being used for graphic-intensive processes, but again, doesn't do much for the h.264.

    8600 does h.264 acceleration under both Linux and Windows, so the card is capable of it. Unless the card is purposely hardware crippled, I'm not sure why Apple has chosen to not enable h.264 acceleration for it.

    Maybe it will be enabled in a future update.

    Yeah I'm not 100% sure on this, but I think I remember reading somewhere that only the 9400 does it. Again, it may be for something completely unrelated though, I could just be getting things mixed up.

    It's only the 9400M.

    Check the feature-specific requirements

    Personally, I can't see why they haven't added support for the 8600M GT and the 9600M, but Apple want to sell more machines, I guess.
