Export multiple artboards {canvases} to separate files

Monika, I have an odd question for you:

How did you come to discover this "Save to separate AI artboards" feature?

I ask because I've recently upgraded to CS5, did a fairly detailed reconnaissance of the menus, panels, dialogs, and tools, read all the relevant tutorials and files, watched a comprehensive video course on CS5's new features. Nowhere was this convenient new capability mentioned.

Did you stumble upon it on your own? Had you read or seen or heard about it in some formal documentation that I missed?

This is not a big deal. It's just that, whenever I discover something like this, I always wonder what other conveniences I'm missing

Well,

you are right, mate! This is really helpful. But what to do, if you are supposed to deliver PDFs for example? {Except loading each .eps and save them as PDF }
