Future's computer!!

I can’t image the computer will change in future. Recently, the revolution of technology is very fast, so I don’t know what computer change, I look forward to seeing the future computer. I think future computers are more colorful and smaller. Then maybe the keyboard is also change because people who often use computer think to type is tired, so the shape keyboard change more useful and they don’t feel tired. Moreover, I saw the article that I don’t know this is true. That said there are looks like 5 pens. If these pens stand on the table, there is keyboard that is light on the table and desktop appear on the wall. I can’t believe!! There is no computer. There are just looks like 5 pens and keyboard and desktop appear that are light. This idea is interesting, but I think this very difficult to realize in the future.
