Computer and Cell Phones

I think in the future cell phones and computers will look and run completely differently from now. I think there will be and Iphone like 20 by then and it will just be like a hollogram projection screen. You would even have to put it in your pocket, it would be able to float. I think computers will become with a very thin screen and will have the same abililities as phones. I also think most computers will have siri and you wont even have a mouse or keyboard, you just tell it what you want to type in or what website to go to, and it will.
