A number of kids also don’t know “file system.” The filing cabinet is a foreign concept, as are many of the now-antiquated technologies referenced/adapted for desktop computing (the address card for your Rolodex, the floppy disk save icon). Tablets and phones are culturally moving us towards stuff being contained within its respective singular app, like all your word documents being within the word app rather than meticulously sorted through layers of folders (even though on the backend, it is). So returning to your first step: why have a browser as the first step when you could just skip having to search for anything because there’s an app? Plus, the delicious unskippable metrics.
