I don't get why kids have such things. Other than typing there really isn't anything kids need to learn that is better done with a computer until high school. (Even then everything could be done with paper, but word processors are useful for writing)
There’s value to technology in the classroom beyond “it’s better than [x]”
A difference in learning format that can be beneficial to some. It is helpful just to introduce children to technology as well. And for some it may spark interests that paper does not.
