iPhone

歴史的背景

Steve Jobs, CEO at Apple Inc., conceived an idea of using a multi-touch touchscreen to interact with a computer in a way in which he could type directly onto the display, essentially removing the physical keyboard and mouse, the same as a tablet computer. Jobs recruited a group of Apple engineers to investigate the idea as a side project. When Jobs reviewed the prototype and its user interface, he conceived a second idea of implementing the technology onto a mobile phone. The whole effort was called Project Purple 2 and began in 2005. The original iPhone was introduced by Steve Jobs on January 9, 2007 in a keynote address at the Macworld Conference and Expo held in Moscone West in San Francisco, California. In his address, Jobs said, "I have been looking forward to this for two and a half years", and that "today, Apple is going to reinvent the phone." Jobs introduced the iPhone as a combination of three devices: a "widescreen iPod with touch controls"; a "revolutionary mobile phone"; and a "breakthrough Internet communicator".
