Computer is a tool for human. As much it is merely used by people. Making life easier and more convenient or making life more complicated and stressful are just different people's divergent views. From the point of my view, computer turns my life into a better one, which is easier and more convenient.   Some of the reasons for the good changes computer has brought to me are obvious. First is in the aspect of entertainment. I can download almost everything through the Internet, such as music, movies and books. Not only does it save the time and efforts to the store, but it also supply enormous sources that cannot be kept in a single store at any time. Besides, some services through the computer are not available in the real market. Take an example: in the computer, I can just buy a single song through the itunes by only 0.99 dollar. And if you are enough luck, you can even download a song you loved freely through the computer. While in the real CD store, if you like a song, what you have to do is to buy the whole CD which is definitely much more expensive than 0.99 dollar.   Then there is trillions of information that can be got by the computer. Before the birth of computer, the ways to get access to information are newspaper, radio, TV. Through these ways, we are just passive receivers. What we get are things they provide. If for some seasons, intentional or unintentional, the media do not supply enough information to us or give wrong things to fool us, it is so hard to approach the truth. Now with the computer, anything is totally different. All kinds of information are available in the computer. What is more, the role of common people is no longer the passive receiver. Through the new tools such as Twitter and Facebook, we, the normal, can provide information to the whole world at any time, at any spot. Anyone can be a reporter. Anyone can make a difference.   More ingredients of computer also make life a better one. In the former time, it is unimaginable for me, a Chinese man living thousands miles away from USA, to listen to lessons of Yale University. Now with the computer, I can watch the videos of excellent lessons not just from Yale, almost from any famous university as far as I can call its name. Through the computer, you can be a perfect person you want to be.   But for some people, computer is too complex and difficult to cope with. And with the easier access to information, someone feels stressful. For me, computer really changes my life into a easier one.
