Messenger Bag in The Devil Wears Prada

Somebody had said it was a Coach messenger bag...but after looking up the brown Coach messenger bag on the coach website, it is definitely not the same. The messenger bag strap in the Devil Wears Prada picture is alot lighter than the Coach one.

Thanks!
 
The messenger bag is definately the Coach Transatlantic Leather Map Bag. I actually have the bag. It is a very nice and practical bag. It is on the coach website under the men's category, under messenger bags.
 
Anybody have any ideas about what bag she's carrying toward the very end of the movie, when she interviews for the new, post-Miranda job? I seem to remember it being green, much more downscale...but it still caught my eye...
