The left one is the equivalent of the single Mac button. The right brings up contextual menus. I always get messed up when I've been away from my work computer for the summer and have only been using my Mac--spend about three weeks, at least, accidentally clicking the right button when I want the left (both computers are laptops, so it's an easier mistake to make). Muscle memory's an amazing thing...
