I think having the option to fit my iPhone into a bag plays a factor into my decision! Slowly but surely moving towards getting the PA once it's available on the website or when the stores open in a month (fingers cross! i miss shopping haha!)I have both in Monogram and I voted for the PA. That is by far my most versatile bag in my collection. I use it primarily as a crossbody bag with my Pochette Metis Monogram strap attached. I have the MP, but I really never use it because it is too small to fit a phone. I know lots of people like the MP to function as a catch all or makeup bag. But, since it is fabric lined and I worry about stains, I use my Toiletry 15 for that purpose because it has a wipe able interior.
