机密三：为紫色项目招兵买马

    2004年，乔布斯曾要求现任iOS软件部高级副总裁斯科特•福斯特成立一支内部团队，其研发项目最终成为iPhone用户界面。福斯特向应聘者表示，“我们将启动另一个项目。这是机密，我不能向你透露任何信息。你要做好准备在接下来几年里加班加点，放弃夜生活和周末的时间。”

Recruiting for the " Purple Project "

    In 2004, Jobs tasked Scott Forstall, senior vice president of iOS software, to form an in-house team to develop what would eventually become the iPhone's user interface. "We're starting another project," Forstall told potential recruits. "It's so secret I cannot tell you what the project is. You are going to have to give up nights and weekends for a couple years."
