We are the most focused company that I know of or have read of or have any knowledge of. We say no to good ideas every day. We say no to great ideas in order to keep the amount of things we focus on very small in number, so that we can put enormous energy behind the ones we do choose.....It's not just saying yes to the right products, it's saying no to many products that are good ideas, but just not nearly as good as other ones. - Tim Cook
