机密四：紫色项目是最高机密

    苹果向来以保密著称，而紫色项目（Purple Project）则有幸成为最高机密。员工们在独立区域工作，苹果还设置了监控摄像头。福斯特称：“我们在办公室挂了块牌子，上面写着‘搏击俱乐部’。”这个名字来自布拉德•皮特主演的同名电影。在一定程度上，紫色项目在模仿这个俱乐部。“搏击俱乐部’的第一条规则是，禁止谈论‘搏击俱乐部’。”

机密五：福斯特的专利

    当用户在iPhone上双击网页进行快速缩放时，他应该感谢福斯特。福斯特在使用iPhone原型机浏览网页时，发现对页面进行缩放以适应屏幕文字太浪费时间了。他在法庭证词中陈述道：“我既然已经拥有了这么出色的设备，为什么它不能自己适应到合适的尺寸。”随后，福斯特给项目团队下达了任务，要求他们找出解决之道。

The "Purple Project's" top-notch security

    Apple is particularly known for its secrecy, but security on The Purple Project went above and beyond: employees worked in a separate area, and security cameras were set up. "We put a sign up that said "Fight Club,'" Forstall said, a reference to the Brad Pitt film, which the team, emulated, if only in part. "The first rule of 'Fight Club' is you don't talk about 'Fight Club.'"

Forstall's patent

    Users who double-tap Web pages on their iPhones to quickly zoom-in have Forstall to thank. When Forstall was surfing the Web on an iPhone prototype, he realized he was wasting time pinching and zooming the page to fit text on the screen. "I realized I have this incredibly powerful device, why can't it figure out the right size for me?" he said during his testimony. That's when he tasked his team to figure out a shortcut.
