I've been recently thinking about this as well! Awesome that you started a thread on it. I remember last summer the buzz was all about the Mini Minis, and I thought they were going to be absolutely perfect for me. I have had a total of 4 or 5, but I have since sold all but one.
I for one actually liked the design change to get rid of the side zippers, as I felt like they cluttered the design of the bag. Removing the zippers was a step in the right direction to make it look more like a MAB, but I wish they continued to go further.
I love how the MAM is a MAB in every design aspect but size, and I wanted the MAMM to head in that direction. I will just never get over the "ear flaps". I want a smaller ring of some sort on the front and the back of the bag (like MABs/MAMs do) to clip the strap to. The one MAMM I did end up keeping has its strap threaded 3 times under the bag, so the flaps don't stick up. But then again, it bothers me that I have to hand carry it all the time now. In the end, no. I thought they were going to be THE RM bag for me, but I am no longer in love with them.
