Should I buy an apple green city & sell my first? I have never seen the city size & I am normally a small bag person being very petite. I have a first, a mini twiggy, small totes, & pochettes. Recently, however, I am becoming more & more curious about the city size. I was thinking maybe I'd like to carry it school w/ a notebook & folder, but at the same time I almost don't want to buy it so I wont carry it to class & get it dirty....what do you all think??
