Right? I own one and this evening I will be using it to get statistics on a 5+ mi group run I'm doing. It's super interesting to get statistics from it, to see how your heart rate evolves, how your pace evolves, but it's also nice to see "fuck, I've walked 6000 steps all day?? Time to move". You can lower your goals on the thing, but your body's requirements are still what they are. I can set my goal to 1 floor a week and .25 miles a month, but that doesn't mean my body will stay healthy if I do that...  When it comes down to it, it's the same as with everything else that could help fats: the only people really benefiting are the people that don't really NEED the devices.
