I work in the world of video by day, but do lots of still image work as a hobby. Even in the world of photography, there is no Mac that edits/filters/transforms/renders 30-40-megapixel Raw images without very noticeable latency. For fluidity and efficiency in what I do, I'd gladly take 10x performance over what exists today on the Mac.
