Bingo. This is exactly it. it makes things more humane. Easier. You don't have to worry about where you saved that file to. There's no accidentally deleting a folder that had an important document among a dozens of useless files.

You don't need to use a clunky device to click on something. You use your finger and you push the screen. Which a lot of people do anyway, to point to something on their screen. Only, it doesn't do anything for them yet.
