A great invention

I think cellphones are the most significant inventions because we can do almost everything with them. Years ago cell phones were only used as devices to do calls. Now, we communicate each other through facebook, whatsapp, line, skype, etc., which are applications that you can find or download in a cell phone, but nowadays you can do different things with cell phones, for example, surfing on internet to look for information about any topic, downloading applications in which you can learn a new language, or simply an application to entertain yourself with a game or one to download music. Also you can do your homework with them, or maybe have your study material in them so that, you can study. Moreover, you can take pictures with them. Another positive thing that cellphones have is that you can use them wherever you are and whenever you want. Besides, everyone can use them; in fact, it is not difficult to learn its use. Simply, cell phones are devices which have made our lives easier, and I think for everyone it is difficult to live without them.
