> which was famously created for the actress Jane Birkin after she complained to the CEO of Hermes that she couldn’t get a bag big enough to hold both scripts and baby diapers. Sure, it’s not as good at carrying things as a backpack, but it’s not bad either.

I checked this out and was amused to see that wikipedia notes:

> Birkin used the bag initially but later changed her mind because she was carrying too many things in it: "What's the use of having a second one?" she said laughingly. "You only need one and that busts your arm; they're bloody heavy. I'm going to have an operation for tendonitis in the shoulder".

In my experience it's pretty common to carry stuff in backpacks. They put a lot of weight on your spine, which can take it. Jane Birkin's comment reminded me of the idea in Dave Barry's Only Travel Guide You'll Ever Need that frequent travelers are always on the lookout for luggage that can hold more than it can actually hold.
