My favourite piece of technology

I think that my favourite piece of technology is my smartphone because it's very useful. Although today is an element very important for communication for everybody, it serves for all. I like the smartphone because I love music and watch videos haha. I travel for 1 hour to university or a little more and I need to do something. Also, I must say that I enjoy playing music for my friends or at a party, I have a varied taste of music for all the time that I spend on youtube haha.
Obviously, I use smathphone for other things but the most part of the time I do it. Really, I still use it for everything. It serves me for inform me and know that be happening in the world. Also, I always have that be connected with my partners of taller so i'ts a piece very important for my academic life. In fact, without smartphones, our life would be very different. Without smartphones, how would we communicate?
