What Will Computers Be Like in the Future?

I think that computers will be smaller and more powerful than now in the future. First of all, I guess that computers will be as small as cellular phones. In fact, there is a cellular phone that can use Microsoft Word and some application programs; however, its shape does not seem to look like cellular phones, and the shape is tasteless. I think that the cellular phone is not worth buying, and I hope that a cellular phone or computer which looks like good is invented and sold. Second, I consider that the future computers will have unbelievable ability of processing. I believe that the computers are quantum computers. Quantum computers exist now, but they have not been perfect yet. The computers can calculate more efficiently than now computers by using parallel processing. However, they are so powerful that we may change now encryption technology. In addition, it is difficult to be put to practical use. In conclusion, I wish that smaller and more powerful computers appear.
