My favorite piece of technology is cell phone. The cell phone is a means of wireless communication through electromagnetic waves. I always have it with me since it is a very important object in my day to day. I use it to communicate with my family and my friends, i f I don´ t know how to get to a place I look for it on my cell phone, to watch movies or listen to music during the trip between my home and the university, in the cell phone I download university material. For this is what I use during every day. I like the cell phone because I used for very things, i t is useful for moments of boredom and study. If my cell phone was not in my life, at the beginning it would be difficult since I'm used to occupy it, but over time I know I would get used to it. Before the cell phone existed, people could still do everything!
