如果你最近去过百货商店,想按照广告去买一部全能型无线通讯设备的话,那么你肯定会失望,因为你所要的型号根本就没有。无线通讯业有一个特点,那就是承诺未来的新技术如何如何,以刺激人们对各种通讯设备的购买欲望。结果,人们涌进计算机商店争相购买带有移动电话功能的个人数字助理(PDA),可以浏览网络的彩色显示屏手机,或者是可以快速下载音乐还可以兼作车库钥匙的MP3播放机。
If you’ve been to a department store lately and want to buy an all-in-one wireless communication device by advertising, you’re bound to be disappointed because the model you want is simply not available. One feature of the wireless industry is the promise of promising new technologies to stimulate the desire of people to buy a variety of communication devices. As a result, people flock to computer shops to buy personal digital assistants (PDAs) with cellular phones, color-screen phones that browse the Web, or MP3 players that download music quickly and also doubles as garage keys.
