Why my cellphone is very important to me?

My favorite technological device is my cellphone, because I use it everyday for fun. Its my favorite device because it is small  and I can take it to everywhere, I can download games and music and use it without internet connection. Thanks to the cellphone I can call to my friends and family, I can read e-mails and watch videos and movies. One thing I like about my cellphone is I can use a lot of social networks apps and share photos and videos about what I like with my friends. My cellphone is very important for my studies because I use it to make tasks and for read books. Also, I can use my cellphone to make videocalls with a friend who lives in other country, he can show me his city and what is he doing at the moment.
