I use it to create on-the-fly flip-books by binding 3x5s together.
When they're spaced out right it's as flexible as a spiral wire
binding, and a bit more durable (not to mention compact.)
Plus, it makes a great poor-man's lamination for printed cards with
semi-permanent information.
You should be able to bind the cover back on by laying it out flat and
taping across the inside of the cover and the 1st page, both on the
front and back. Then you'd have to work the binding a little bit and
perhaps set some giant ancient codex on it to break it in.

So it's now retired. I picked up a pocket reporter notebook, because my
big frustration with the regular pocket ruled book was that it was hard
to write while walking. But I don't know if I want to keep carrying
that around in the same way that I carried the previous notebook -
leaving it to back pocket abuse.
So when I picked up up that notebook I also picked up some Cahiers.
They're about 1/3 the size. The Cahiers just have a paperboard cover
though - not that nice sexy moleskine cover (I think the volants have a
soft moleskine cover at the same size of the Cahiers). So they're not
quite as protected, but at their smaller size they're probably easier
to fill up, easier to carry in a back or side pocket, and you can get
yourself to that "new notebook smell" quicker.
