I think you are looking at the wrong thing. That's like looking for Symbian qualities in an iPhone. I mean, what you need is a productive pointing device not specifically a touchpad and for that the TrackPoint in ThinkPads still wins.

No, what I need is a way to scroll effortlessly on a laptop.

This unfortunately almost purely a software issue and with Apple having a tight grip of their developers they can easily make them support their trackpads well.

On Linux, with modern GTK apps, scrolling up and down has become pretty nice. Scrolling in other directions is still not certain and zooming is out of the question, though.

On a properly configured Thinkpad, hold down the middle button, and scroll with the TouchPoint without leaving home row.
