The ScanSnap Organizer that comes with the ScanSnap is actually pretty good. Other than that, Windows 7 will index OCR'ed PDFs so you could do the same sort of thing as the article without needing "extra" software.

One thing I really like about his approach is he keeps it simple: instead of going crazy with a folder structure he relies on search. Instead of using some complex software product, he uses Spotlight. Very nice.

I just know that I'm too lazy to make some complicated scheme work. I'd just end up with stacks of paper that I intend to scan "someday".
