My favorite piece of technology is my mobile phone. In fact I`m not very proud about that, but it`s the truth. I remember being in highschool and my parents wanted to buy me one and I always told them not to, I dont`t want it, I dont`t think it is useful, I will lose it, etc. After like 6 months, I decided to have one, and unfortunately now I can`t be without it.
I forgot all the phonenumbers of my friends and relatives (because now you look for them in the mobile), if I`m not with my mobile I can`t call anyone, besides I`m not at home very much so this piece of technology really makes it easier in many ways.
Obviously not everything is perfect, sometimes you lose your mobile and you have to call to the company so they block it, sometimes it drops out of your pocket and may break down, also there are always some people willing to take it.
The mobile phone, I use it everyday, most of the time sending messages (it is cheaper), and for instance when i call my parents or some relatives I just give them a ring and wait for them to call me back.
Well I said before, I`m not very proud about all this mobile thing, but definetely I think it is the most useful piece of technology I got.
