I don't think that paper books will exist for ever. They are more expensive than electronic books, they need much more space and often are rather heavy. It's unpleasant to read paper books when they become old and rather dirty.
I can see why some people think that computers will soon replace books. It's an inevitable process. If we have a look at the history of books we will see that they were the main sourсe of knowledge, but today everything has changed. We get much information using our computers. Computers take less space and can contain thousands of books, that's why they are so popular. In my opinion  sooner or later the right place for paper books will be in museums! =)

Hi, Jane! Last month I went to England with my aunt and dad. It was very interesting travel. English people are friendly and polite. We visited London and Liverpool, where my cousin lives. London is very beautiful city. It has a lot of showplaces. We visited Big Ben tower, Tower bridge, British museum and other landmarks. I was very interested by Sherlock Holmes museum, but we had no time to visit it, because my cousin was waiting us in Liverpool. In Liverpool we walked a lot, it was very funny because my cousin has a good sense of humor. I think, that's all. Please, reply me as quick as you can. 
Your friend, July.
