What Will Computers Be Like in the Future?

Today, the development of computers is terribly fast. New ideas and computers appear everyday, and disappear soon. At the information technology revolution, a large amout of computers were produced as same as other industrial merchandise. However, this mass production will be over. In these days, it has been changing that people want computers to be. People have become want to get just they want. Then, if customer's thought changes, computer companies have to be change. I think the relationship between customers and compnies are changing. And, it will change the existence of the computer market. The custom-made computer will be normal. In addition, I think computers will be more flexible, and portable than now like cell phones. Then, cell phones may unite with computers, and we may become able to use the Internet, and other programs on our portable device. It's interesting, isn't it?Finally, I think computers will be like all-purpose device in use.
By the way, have you ever heard quantum computer? Actually, I don't know well, but if quantum computer was realized, the world would change.
