Using a computer, good points and bad points

I think that to use a computer's good point is, wherever you are, you can contact your friends all over the world. You can contact whenever you like. The other good point is you can search whatever you want. If you want to some clothes, but you can go to shopping, you can buy their in her house. But it has some bad points too. When the computer broke, all of the date in the computer was delete. It is too bad. The date can't come back again. There is nothing you can do. It is one of bad point of computer, I think.
