MOTOROLA DEMONSTRATED THE VERY first handheld mobile phone almost a half century ago. It was the size of a brick and weighed half as much. That prototype spawned the first commercial mobile phone a decade later. It, too, was ungainly, but it allowed a person to walk around while sending and receiving phone calls, which at that point was a great novelty. • Since then, mobile phones have acquired many other functions. They now have the ability to handle text messages, browse the Web, play music, take and display photos and videos, locate the owner on a map, and serve countless other uses—applications well beyond what anybody could have imagined when mobile phones were first introduced.

显示弯曲和拉伸：一些智能手机现在可以像钱包一样折叠。几年后，你可能会在你的皮肤上戴一个

近半个世纪前，摩托罗拉展示了第一部手持移动电话。它有砖块那么大，重量只有砖头的一半。十年后，这款原型机催生了第一部商用手机。它也很笨拙，但它可以让一个人一边打电话一边走来走去，这在当时是一个很大的新奇事物。• 从那时起，手机获得了许多其他功能。它们现在能够处理短信、浏览网络、播放音乐、拍摄和显示照片和视频、在地图上定位所有者以及提供无数其他用途——这些应用程序远远超出了人们最初使用手机时的想象介绍。
