Someone can correct me if my logic is incorrect here, but I noticed when reading about Snow Leopard that the Nvidia 9400m supports H.264 hardware decoding for Quicktime X. That takes load off CPU and allows GPU to deal with video while CPU is available for everything else. Now, wouldn't animation in Flash ideally be able to be managed by the GPU also?
Apple has really made the MBA incredible with the 9400m. Between Snow Leopard, Nvidia 9400m, and SSD drive the MBA is an absolutely amazing Mac. I am so amazed by my MBA, and it just keeps getting better. Will be nice if either Apple or Adobe can figure out how to offload Flash work to GPU. Again, I don't know the specifics, but the 9400m impresses me time and time again.
I think the rev B/C MBAs are incredible little Macs. Their hardware is solid and the picture keeps getting better. Go MBA, GO!
