Apple currently sells two laptop lines. The MacBook Pro and MacBook Air. The MacBook Pro comes with a 14-inch or 16-inch display (there used to be a 13-inch MacBook Pro, but Apple discontinued that model) and the MacBook Air with either a 13.3-inch display, 13.6-inch display, or a 15-inch display. That is a lot of Mac laptops, and among those models are an even wider range of specs.
