I think computers are very important in our lives nowadays. I don't think anyone could live a single day without a computer or a laptop. If, let's say, 10 years ago, computers didn't matter to people as much as they do now, I don't think they do the same thing today.
Firstly, it's a lot easier to comunicate with people by using a computer. You can use sites such as Facebook, Twitter and many more.
Secondly, you can find the information you need much faster than you'd do without a computer.
Finally, computer is the main source of entertainment. You can play games and watch different movies on a computer.
So yes, computers are very important in our lives.
