The ThinkPad X1 Carbon has a trackpad of quality equivalent to the MacBooks, just look at reviews online. Plus you get the TrackPoint, which is much more efficient once you get past the learning curve.
and then comes the amusing lack of proper configuration on the OS side. I am not an Apple person, but I have yet to see a trackpad- configuration that works even remotely as well as the MBP ones. The speed and acceleration multipliers in there have always been off.
EDIT: +1 on the NavPoint. I disable the trackpad on all my thinkpads and just use the NavPoint whenever I can.
