I saw this very nice review on Youtube about a 38mm Sport with White Sport Band. She was wearing it on her right wrist( I thought it looked good upside down). She even talked about Wifi working keeping the Watch connected to the even if out of range with bluetooth. She went into a lot of detail of other things.
Take a look.
