Actually I'm using a Macbook Pro. The problem with messing with scrolling is that my usual flick of the trackpad does not get me to the point that I expected to reach on the page. It's very mildly disorientating. I was going to scroll down to the next section on your page anyway, so there doesn't appear to be any benefit in dictating exactly where I scroll to. Unless you have a very specific reason for overriding the scroll behaviour (eg. an interactive story), it's best to steer clear of it.
