Goldilocks! Love it!
I think part of the reason that the LeP is so popular could be because it folds up, so it's easy to carry as an extra bag. That said, I rarely use mine as it's just a big, unstructured black hole. And I have other "extra" bags that I'll choose to carry that will take up less space.
I find that the leather straps will slip off of my shoulder, which is annoying. The LeP is a pretty bag, and I'll use it on my daily commute when I have something large to carry.
But for travel I need external pockets, a sleeve that will slip over the handle of a suitcase and the option of a cross body strap. I have a bag by Lipault that hits all of those notes, but isn't as aesthetically appealing as the LeP.
