I've watched the video and read the reviews and it really seems like a great practical, all purpose bag that I can also use as my purse, and that the hubby can also carry without feeling goofy. It includes a changing pad, stroller straps, messenger strap, it converts to a backpack as needed, has cooler compartments, bottle pockets, laminated easy to clean interior and can even fit a 13" laptop and a yoga mat - I love it!
It's $175, not cheap, but I think it's the one! The only question is black or slate? Probably black, but luckily I have time to decide!
