From these statistics, we can know more and more people have already changed their original communication into this convenient manner gradually.
But why does the cell phone gain so much dominance in our lives There are mainly three factors accounting for this. Firstly, a cell phone has no wires and can be carried everywhere easily. It is smart. If you need to ring someone, you can just dial a number and the phone will connect you to the right person. It can be a great help for you to be connected with the world. Secondly, a cell phone is something wonderful that we can have fun with, for instances, we can browse news, play games, listen to the music and chat for its simultaneous improvement in the functions and connection with the Internet. Thirdly, the drop in price makes it possible for an average person to use a cell phone.
Of course, any new invention has its drawbacks, but such negative aspects cannot always diminish its popularity. As far as I see, with the introduction of new techniques in future, mobile phones will have more applications and become even more appealing to customers.
