Nowadays，with the rapid development of it and information industry, cell phones play a dominant role in towns people's life. But, like everything else, they have both favorable and mffavorahle aspects. First, it's useful. As a wireless mobile telephone, it's easy and handy to early to wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people's life. Second, it's convenient. Whenever one meets trouble or something urgent, one can nmke a call immediately. Most important of all, it's a very helpful companion. With a multirfunction cell phone in hand, one can easily get on the net, browsing the useful information, conducting e-commerce and doing whatever one can do via internet.

　　However, just as everything has two sides, the cell phone also has many disadvantages. To begin with, it's expensive to buy and costly to pay the hills, esp. That of global service. To make matters worse, it's also easy to lose and costly to get it repaired. Worst of all, it's not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it's alleged the microwaves in it might do harm to people's health. In my opinion, with its expenses greatly reduced after china's entry into the WTO. It will face an ever brighter future in its development. Someday most of them will be developed into new intemet-enabled mobile phones, which will be as useful as pocket computers. And i believe its advantages will not only offset its disadvantages, but also far outweigh them.
