I actually haven't used half that stuff yet, just discovered the depth of spring loading and the weird objects it supports (contacts / maps) while I was writing that comment. But even for smoother handling of text, images, and PDF files I really like this feature.

As a downside, the interface for picking up multiple objects feels a bit weird and is probably one of the bigger learning curves that iOS has gotten.

Another example I just found - you can drag an email (or several) from Mail over to Documents where they're saved as .eml files. Documents doesn't know how to render these so you see the full markup, but I can imagine that would be a useful feature for something.

Maybe a utility app to view full email headers? I don't think Mail.app has a way to get into those.
