Do you have smart phone? Probably, most people will say yes. As we know so many people cannot live without smart phones. From the smart phone, we can see high technology is very powerful and popular. Almost all the teenagers have smart phones. We can see them use smart phones all the time. So many parents are worried about their children always hold their smarts phones. However, those parents don’t realize that they also use their smart phone for long time. The problem is smart phone is good or bad for people is this society. 

            I think the smart phone has so many benefits. As we know the smart phone combines the functions of normal cell phones and computers. The smart phone makes people’s lives easier and convenient. “Before smartphones, people used cell phones and PDAs, two separate devices that did very different things. Cell phones had the limited capability of making and receiving calls, while PDAs featured a date book, address book, task list, and memo pad. These portable organizers also worked as handheld computers, performing simple word processing and spreadsheet functions.” (Smart phone). As we know the smart phone is very useful. All the functions were put into this small box. We people go outside, no one want to bring the laptop, that’s too heavy. We almost can use my smart phone to do any work. I can do my homework, online shopping, GPS with my phone. The most useful thing is we have internet date in our phones, such as LTE. If there is no Wi-Fi, we also can use our phone, but computers are not. Also there are so many apps that I can use. I can watch news easily, we can shopping use apps. We also can apps to call the taxi, the most famous apps is uber.

  The smart phone also helps the economy.With the smart phone, the e-commerce become normal, so many people use e-commerce to make money "As a result of smartphones and their multitude of apps, the e-commerce industry exploded, and a new generation of consumerism emerged: mobile e-commerce.""Smartphones have contributed to the growth of mobile e-commerce in multiple ways. Consumers can make purchases using mobile devices by directly visiting a retailer's Web site, linking to sites through apps, and bidding on eBay, among many other methods. Growing numbers of retailers are designing Web pages specifically for mobile screens, making it easier for customers to purchase merchandise directly from the retailer's site." (Smart phone) . We know now the famous smart phone companies are Apple and the companies with android system. Does anyone remember the company calls Nokia? "Nokia Corp. has stood at the pinnacle of the cell phone world as the world's largest manufacturer since it surpassed Motorola in 1998."(Nokia). This company was almost the no.1 company, before. however, when the Apple and android system become popular. So nokia and Microsoft get together. As we know more companies focus on how to improve their products. Technology are getting better day by day. And also before the smart phone became popular, most people used Nokia, I also love Nokia. However, after the smart phone. So know more and more people spend more money to buy smart phones. Also because the smart phone update so fast. Many people buy them for fashion.

            However, many people have some problems with using their smart phones. More and more people use their phone for long time and rely on their phone too much. Using the smart phone too much will waste people’s time and money. As we know the smart phone brings people convenient and useful, but that also makes people hold their phones all the time. People rely on their phones. When people face problems or they want to find some information. They just use their phones without thinking. When the smart phone become “smarter”, humans become stupid. Other problem is people use their phone for long time, they cannot finish their work well. For example, when I want to do my homework, I use my phone to find the words. When I start to use my phone, I cannot control myself. I start check my email, Facebook, blog, and sometime play games. After that, I realize that I didn’t finish my homework. In addition, when the new smart phone comes out, many people buy the new one, even though their phones don’t have problems. 

Sometime hurt people’s eyes and health. People are always on their phones, that hurts their relationship. When I walk in the public area, such as, bus, subway, restaurant. I see many people hold their phones. Even their friends sit together, they don’t have any conversation. When I go out with my parents, my friends or boyfriends, we don’t talk for long time, we just hold our phones. I remember when I was in China, my mother and I stayed at home, she used her phone to send a message for me and asked me “what you want to eat for lunch”. However, my mother doesn’t like me to use my phone for long time, because that hurts my eyes. I know, because my eyes are worth every year. Also I feel pain with my cervical vertebra, after I use my phone for long time. Smart phone helps people a lot, but if we don’t use it well, it may hurt us. 

            In conclusion, we know the smart phone has two sides, it has so many benefits and disadvantages. I think it depends on how people use it. We should use the smart phone in right way. The smart phone is very useful for people connect to each other, find information easily, and help economy increase. However, if people rely on the smart phone too much, people will be addicted to the smart phone, using the smart phone for long time is bad for people’s eyes, and cervical vertebras. Also people will waste money to buy the new phone for fashion.  People should treat the smart phone in right way. However, the smart phone really changes people’s life.
