Are we too dependents on computers?

Since we are able to have a computer in each house, the use of those machines has taken a lot of importance in our lifes. The computers, allow us to get acces to a lot of information and entertainment, at any moment.
The computers have a lot of purposes, the majority of the people use it to enjoy the vast oportunities that internet has to offer to us, as social networks, and videogames, for example.
In the other hand, the PC is a work tool too, we can use it to make our job easyer, doing difficult calculations, or ordenating our work in a simple way.
Of course, I think that we are dependent to computers, because they have taken a huge importance in our lifes.
