機密四：紫色項目是最高機密

????蘋果向來以保密著稱，而紫色項目（Purple Project）則有幸成為最高機密。員工們在獨立區域工作，蘋果還設置了監控攝像頭。福斯特稱：“我們在辦公室掛了塊牌子，上面寫著‘搏擊俱樂部’?！边@個名字來自布拉德?皮特主演的同名電影。在一定程度上，紫色項目在模仿這個俱樂部。“搏擊俱樂部’的第一條規則是，禁止談論‘搏擊俱樂部’?！?/p>

機密五：福斯特的專利

????當用戶在iPhone上雙擊網頁進行快速縮放時，他應該感謝福斯特。福斯特在使用iPhone原型機瀏覽網頁時，發現對頁面進行縮放以適應屏幕文字太浪費時間了。他在法庭證詞中陳述道：“我既然已經擁有了這么出色的設備，為什么它不能自己適應到合適的尺寸?！彪S后，福斯特給項目團隊下達了任務，要求他們找出解決之道。

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.
