Cell phone

Nowadays, there is no limit to technology. New advances and techniques are produced everyday. For teenagers, it's always nice to know about it and to have as many gadgets as possible. Among the gadgets they usually have, there are the useful ones and there are the ones they'll never need. In my point of view, the most useful gadget for a 21st century teenager is the cell phone.

A cell phone offers lots of advantages, starting with the most important one: making and receiving calls. It may sound a little obvious, but that's the only way to talk to someone whenever you want. Of course, you can talk to a person using a computer, but only if this person is online too; with a cell phone, you can contact him/her anytime.

Another advantage of the cell phone is that it has a lot of tools in it. Therefore, other gadgets can be replaced by only one cell phone; for example: you won't need a camera or an mp3 player if you can take pictures with your cell phone and listen to music in it. Depending on the cell phone, you can also make videos with a great image quality.

Well, these are the reasons why I think the cell phone is the most useful gadget for a 21st century teenager. I believe that by the end of the century, more gadgets will have been invented. Nevertheless, cell phones may be considered very important for the technological advances.
