Do you know the history of cell phones? The first cell phone was invented in 1973.At that time, it was as large as a building brick and much heavier than the cell phone today. Now, cell phones have many uses. For example, we can use cell phones not only to talk to others, but also to take photos or listen to music. We can even pay by cell phones. I believe that cell phones will become thinner and thinner and they may take the place of computers in the future. $$
