Laptops are certainly useful. They make our life easier and more simplified. We can use a laptop as a book, as a tape recorder, as a dictionary just like I use. And it saves our time. But there are also disadvantages as well as advantages. Among them are a harmful screen. As a matter of fact it really spoils our eyesight which is difficult to restore. It's necessary to use laptops within reasonable limits. Another disadvantage is that laptops and technical equipments in general gradually replace books, our national property. Books take second place nowadays. All the same,I think, books existed, books exist, books will exist.
