I don't know if is my favorite piece of technology but what I use the most is my cell phone because is multipurpose, in it, you can use it as a calculator, alarm, camera, perhaps as a small computer because you can for looking in the internet different information and the main purpose that I give is communication with my friends and family when I am not whit them. I use my cell phone every day so I carry it with me always although I don't like to depend on my phone, but it helps me a lot to do some jobs faster.
I think that someone depends so much of the technology is very bad for the relationship that he makes, in the social relationships, in the family and all fields where there is an interaction face to face.
There are times where I have been without a cell phone, where I don't feel the need to take it with me, but nowadays, within the university, it would be impossible to be responsible and to know information about the different subjects.
