Electric Baby Scale

So do you really need a scale for baby? I think not, but if I were going to get one, it would be this one from Petit Terraillon. The techie part of me really likes the memory function on it, that can calculate the difference in baby's weight. And if baby wriggles and moves around the scale has a freeze function making it possible to weigh a moving baby. You know, come to think of it, my doctor's office doesn't even have a scale as technologically advanced as this one....
