I think computers and cell phones in the future, say 50 years from now, will be more extremely high tech. I believe that the computers will be not only touch screen and voice activated but will also be about the size of a cell phone and you will be able to just hit a button and it gets bigger. When it comes to cell phones i think they will be soo big you wont be able to fit them in your pockets and they will talk to you and have a normal conversation just like a human.
