I have the X3100, I am sure that the drivers have been updated since I can now view trailers in 1080i with a smooth framerate! 😀 Some animations are still choppy though.
I meant, that I still cannot run the display in thousands of colors which is required by some games and apps. Kinda a bummer, and some games still won't run that ran on my previous macbook with the gma 950 just fine.
