The who cares is presumably that it can improve people's lives if they knew about it. I have to say that his description of his wife fits my iPhone use as well. As for the App Library, it is not discoverable if you have many pages of the Home Screen which can be true for those of who have an iPhone for a decade or so. The real trick is apparently to learn how to hide those home pages, then it becomes discoverable. I do think there is a terminology issue with the Home Screen being used for multiple pages. That is just confusing. As for the long-press, I accidentally do that all the time.
