I'm waiting to see the Neo Cabby in the new Rose color coming out in April I believe.
I thing both bags are absolutely stunning but you'd probably get more use from the Trevi because it's more of an all weather bag and can be dressy or casual, the Neo Cabby would appear to be more on the casual side. I plan on getting both at some point.

I would choose the Trevi. I just can't get over that the neo cabby is denim....!
