I agree with tkubacki, touchpads on macbooks are a primary reason for wanting a mac.

For me the most important is the basic function of putting the cursor where I want it. It's hard to explain, but on other laptops I always struggle with it either being to slow or to fast, general responsiveness or just the miniature size. Apple touchpads for me are a "it just works™". I barely use multigesture, but they work as expected as well. Also for me the force touchpads are blissful, you can just 'click' by pressing anywhere and you get haptic feedback indistinguishable from a hardware click (I loathe tap-click touchpads btw, they always click when I don't want to).
