I am trying to decide between these two bags. They seem similar in size. I love the cherry color on the bianca. I have that bag but was considering the nomad instead. Which is more funcitonal? anyone have the nomad? what does the expandable front pockets mean? and does it close with a magnetic closure verus the turnlock on the bianca? I also want a sophie in raisin but can't find it. any opinions will be helpful!
