I have a friend who just got back from the states.
She tells me she saw a bathroom scale at the airport that can record your weight and BMI and somehow transmit it to a Computer or an IPhone and keep a graph record. She was late for her flight and can't remember what it was called or who makes it.
Well it's Xmas and it seems like a great idea!
Anyone know what I'm talking about / have one / know where to get one in Oz?
