We know how use the technology?

If we talk about technology, people usually think in progress, speed, computers and a lot of things like that. But, I think that everything that goes round us is technology, because any object that can satisface a necessity can be a piece of technology.
I'm not really sure about what is my favourite piece of technology, but if I have to choose one, I choose the cellphone because it allows to make calls, connect to internet, take photos, listen to music, record voices and videos, etc. Also, it has a gps, and I think it is amazing to be in a place that you don't know, watch your cellphone and know  exactly the place where you are, where the bus stops, where the more interesting places are, etc. Or If you are traveling, the gps is a very good complement so you don't get lost. 
Well, the cellphone is multifunctional and it permits you to be connected all the time, but you have to be careful with it, because most people are obsessed with this and so many times they don't hear what you say and don't see you when we are talking. The idea is to use the cellphone like a tool, not like a life controller.
