Yes, Steve, you are welcome to use my comments. When I first learned about SPJ many years ago, I read that his special talent was his charismatic ability to inspire developers. This is a theme that runs throughout Walter Isaacson's excellent biography.
I used to be a meeting leader for a Mac user group in northern california, during the years when Jobs was in exile. Most of the audience consisted of seniors, average people who struggled to make their Macs behave without crashing. In those days, I became expert at managing the system extensions and control panels, plus all the other special precautions we had to take with limited memory and hard drive space compared to what we have today. I remember asking for a show of hands once, to indicate how many in the audience had ever been beta testers for Apple - then I held up a CD-ROM of the "new" Mac OS 8.5 and told them that for $99 they could be beta testers for Apple. It was such a buggy release.
Then I would ask people in the audience if they had ever used the Finder's Put Away command, which I had seen Jobs demonsrate somewhere, back in the days of System 6 or 7. The concept was brilliant: drag all your stuff out to your desktop and then when you were done for the day or whatever, you could Select All and execute the Put Away command and every single item would go back where it came from. It always astounded me how few people knew that the Put Away command even existed, and when they saw it demonstrated, they gasped at the thought of how much time they wasted without using it.
Here we are 20 years later and our ultra-modern Unix-based operating system can't do that task. Jobs had the ability to envision, the way Buckminster Fuller did, how to add up all the wasted time every day in the world consumed by people moving stuff around on their computer desktops, trying to stuff things back into folders. So when it came to iTunes and other programs that work with a specific file type, he made it unncessary to concern yourself with a filing system.
In the iOS, things work that way. Users find it a little confusing with the PDF's that they want to add to their iBooks interface, for example, but you can see how iBooks worked like iTunes in terms of document management and how they had to revise it when customers wanted to have their PDF's on a bookshelf, too.
Unfortunately, when you create documents in Pages, Keynote, Numbers, Text Edit and other programs, Apple can't as safely predict where you want to store them, and how you want them to be organized. Maybe you want folders for your clients, or folders for your projects, or whatever. And that's a segway into the discussion about how the desktop computer is unlike a mobile device, which is the heart of this discussion.
