Hi-tech products---convenience or troublesome

People always refer to digital era as a description of the present time. Digital, as a form of technology, penetrates our daiy lifes. Once, a teacher of mine said chalks are strangers to him simply because of the keyboard of computer. A joke? No, a tragety indeed. Advocaters especially the "native of digital"(people who were born after 1985) proclaim the indispensable functions of such and such technologies while the opposing side decry the negative effects (eg. health problems) which those tecnologies caused on people. I belong to the neutral group and tend to believe technology, being used as a tool instead of our master. Here, I will take mp3 for a typical example and mainly focus on its virtue and vice.

Mp3(and the recent mp4), a popular digital audio encoding and lossy compression format, can also mean the broadcasting device, such as ipod, yepp. Because of its versatile attribute, people use it as a mini music player, a radio or a removable disc. Receiving subscribed news from the internet, a great platform for mp3 file music and also wma, acc, mp3 operates like a medium between huaman beings and digits. More, it itself represents a sort of culture. On the street, subway, everywhere you can spot folks with their earphones on, swinging or murmring.

Mp4 even joint with "some"Tv corporation, provides "wonderful" soap operas to its audiences.
What a giant media net!

There is usually a "however". I recently came across a piece of news talking about the side effects of ipod. Not only will people generally get the hard-hearing problems(which also exists in cd player), but can also suffer from what is now called "ipod hands". According to the English Vertebra Nerves experts, frequently unnatural movements adopted by thumb and the rest of the fingers can cause arthritis. In some serious cases, pain spread up to neck and elbow.

Lots of similar harsh reality illustrate the abnormal relationship between people and technology: they are dependents of the technology!

Mind everyone and myself, try to be a smart user.
