Honestly, I like theCabas Piano despite the vachetta bottom. It may not hold a lot because it's very structured, but I think it would hold a tad more than the PH. It's also a bag you don't see too often, and I'm sure you could fit a skinny notebook in there (at least, according to louisvuitton.com). The size is also not overwhelmingly large so it'd be a good size for shopping as well.
I used to want the PH but after walking around Newport Beach and seeing every two women with one (no joke), I didn't really like it, anymore. And the clacking balls on the zipper pull annoyed me whenever a woman/girl walked by really fast.
BH is a good bag if you carry a lot. It's not a personal favorite of mine but it seems to be an overall favorite in the board. What I like about this bag is that it's not too big/not too small on the frame (unlike the Cabas Mezzo or
the Popincourt Haut).
