Computers are to facilitate office and research work they should not be placed at home. This statement is very controvercial. From one point of view it's absolutely right. People should work at their workplace and computers there are of great help. They can help people to find necessary material for tgheir research and what not. It's easy to type using the computer and to exchange information. But I think that computers must be at home too. Different ideas may come to people not only at their workplace but at home as well...and here we need a computer to help us. Of course if we use it only to play games, then we should not have it at home because it's a waste of time. So to sum it up I should say that if you use computer properly it doesn;t matter if it is at home or at work. And if you don't...well, then it's just your problem.
