Most natural to use the track pad is to curl my right hand towards me with my wrist still touching the macbook. One finger feels decent, but already 2 fingers feels a bit off to me. And 3 fingers even worse. It's really stretching my wrist at that point. My wrist is always positioned on right of the trackpad, but putting 3 fingers on the trackpad is putting it at an uncomfortable angle.

Even with one finger I think I have to bring my wrist quite away from the usual position though, off the laptop with its bottom. But three fingers feels uncomfortable even when I do that.
