Technology ☏ Cell phone ☎

With the science and technology developing, more and more new electrical appliances come out. Cell phone is one of the most important things in my life. And it is one of the most useful and helpful things. I cannot live without it. As everybody knows, cell phone is used for contacting each other. It is convenient to take everywhere. If I have something to tell others immediately, such as I want to inform about something changed or I want to tell my mother where I am. I can use it whenever I want to. Many of the cell phones also can be used as a camera and an mp3. So I think cell phone is the most important technology for me.
