apple 不想公佈實際的specification 原因
因為apple 的marketing strategy 是humanized technology experience，不想別人在意iphone 的specification ，從而比較硬件上的分別，因為想sell better user experience, user friendly，令user把iphone 和其他的smartphone 分開看待。
Apple doesn’t want people to think about their products as the sum of the parts but as a more humanized technology experience. And, as such, it takes a different approach to both building products and marketing them.
