I actually came to comment on this matter. Anecdotal evidence of several people I know is that playing FPS games with trackpad (pretty much of a torture) improves touchpad intuitive usage to an extent where they don't notice any discomfort with it in daily life.

Perhaps, hand-eye coordianation training that happens in FPS shooters translates to better touchpad usage in normal cases.

(Still, I'm told that trying to competitively play FPS games with it just sucks).
