What man doesn’t live in fear of the dreaded Costanza wallet and the inevitable fallout from such monstrosity?  I’m guessing not many, since entire companies have been created based on this fear and embarrassment. Dramatics aside, Coin seems amazing even if you do not care about a large unsightly wallet. It is brilliant in its innovation and execution alone. Excited about the brilliance that is Coin, I rushed to share the news with one of my closest female friends. Yes… the very young lady who jumped atop my Tom Bihn BrainBag with Macbook Pro inside. Needless to say, I was met with some pushback.
