What will computers be like in 2050? (5-7 sentences)

In my opinion in future our familiar gadgets will be completely different. As for computers, i think their screen will be thin and large, and keyboard will remind light projection. Also it won’t be any mouse, only touch screen. They will be able to do new functions, for example finding person in any area by voice. Nowadays not every family has a computer, but I am sure, that in 2050 it will have.
