It's pretty neat, it provides a lot of detail on how much fat and muscle you started with as well as the weight of all your organs, and body water. My scale at home does similar measurements, and while the numbers a slightly different that what I get at the hospital, it's been a good guide to watch trends, which end up matching the hospital readings.
It also compares your muscle mass to people of the same age range and sex, which I though was good info.
It actually influenced me to increase my weight training a bit after my 3 month appointment because my ratio was just under 2:1, so I worked to increase it and it seemed to pay off.
