I can't possibly imagine how any phone could be smoother than the Galaxy Nexus. Yes, it's taken a long time to get it in 4.0 and it's available to almost no one, but it is finally fixed in my opinion.
I agree that the scrolling is pretty smooth. It's not quite as smooth as I think it could be but it's far beyond acceptable. I think when people say that scrolling doesn't "feel right" on a Galaxy Nexus is because of the distance you have to physically move your finger before it responds and actually starts scrolling. I think this is deliberate to prevent people from accidentally scrolling, but nevertheless, I think this is what people are seeing.
