note: you can't tell from this photo but the new MB2 will lay flat on it's own, it's not a ridged and hard angles like he old ones, it really fits over your wrist well. I hate things on my wrist so this will be turned into a key chain and for now i'll probably just carry the icon (puck thing, official name) in my pocket.
It is a nice conversation starter though and you quickly learn who is paying too much attention to you.
