The Effects of an Invention or Innovation in Modern Life. (final)

In modern society, the most convenient product that I thought is "cell-phone". I remember that we did not have cell-phone few years ago, and it is very difficult to contact our friends. As long as someone leaves home, it is very hard to find the person. When cell-phione is invented, I find that it really saves so much time and convenient.

Now a cell-phone's function is not only used for contact but also looking for some information. With technical development, cell-phone has increased a lot of functions, for example, MP3, taking the picture, surfing the Net, editing your cell-phone and so on. It becomes a necessity in people's life. Due to the popularity of cell phone, the price has also become extremely cheap, so it cannot become a burden in our lives. But the phone bills really need to be controlled, although the rates are not certainly expensive. If you uses it to for chatting, you may cost a aly lot of money in a month. Just like me, my phone bills are 1500NT dollars this month. Therefore, I have to watch out my phone bills more than before.

It is very difficult to imagine that if we do not have cell-phone in our lives. It is not really convenient. I think I am really fortunately to be born in this century . The cell-phone is really interesting. I can play games by using cell-phone when the class is so boring. Playing games by using cell-phone also may kill some leisure time. I think it is really a quite good invention.
