Any thoughts on LV Coussin?

Sorry, everyone....now I am jonesing for the Popincourt Haut!

What is better, the Popincourt Haut or the Coussin? I want an everyday bag for work and for going out. I am petite (5'). Maybe a special order in the Damier or even Epi? I really want the perfect black bag from Louis Vuitton, all the Epi bags are either too small (pochette) or too big (croisette).
 
I like the coussin, but I wonder about the wear and tear on the corners. It doesn't sit up on its own like the popincourt (I'm assuming), so you'll have to lay it down on one side when you're not carrying it.
