The "find it later" part is kind of important.

Agreed. The average user loses a file when it falls out of the recent documents list, so it'd be nice if a power user at least had some clue where it might be found. Windows "search" is also buggered, as mentioned in the article, and only shows a handful of documents and a thousand irrelevant Bing search results when you're looking for a document.

Of course. But "remember where you placed the file in this filesystem hierarchy" isn't the only way to accomplish that.
