It may be specific to my MBP model (17" Core i7) which has the weirdo combination of Intel and Nvidia GPUs that are switched flakily in software at OSX's whim and Chrome has been known to trip the GPU switching - http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=chrome+osx+gpu+switch http://www.google.com/search?sourceid=chrome&ie=UTF-8&#3... . Scrolling was very jittery in general and page rendering/painting was also slower. Not like molasses slow but definitely not acceptable for a Core i7 machine. With Win 7 which uses only one GPU, the Nvidia one, it is very smooth and fast as I said - definitely wouldn't want to go back.
