I look at this and think "finally, someone's found a way to capitalize on the disposable income of people whose homes are already full of exercise bikes being used as coat hangers and whose wrists are nearly ready to collapse under the weight of their fitbits, pedometers, and GPSes."<p>Here's the secret to health and exercise: you have to want to do it. Another $100 device to tell you "you're still not doing the thing you said you want to do but that you're not making time for" if it's not something you want to do. I run and love to do it. Here's how I know I'm different from other people this way: when I started running a lot (about 6 years ago) I would ask friends if they wanted to go for a run and they would say "no." I wanted to get fit, but I also wanted to run. I know people who ask "how can I run more?" and I ask "well, do you enjoy running?" and usually they say they don't. I don't tell them they need to buy different shoes or gadgets to try to coerce them into doing it, I suggest they look at other kinds of activities that will fulfill them and try to incorporate that into their life.<p>I believe too many people confuse fitness with the <i>goal</i> of exercise. Happiness should be the goal. It's fair (and probably right) to say fitness will bring happiness, but it's important to keep those in perspective and realize that if exercise (a means to fitness) isn't bringing happiness, then maybe the exercise should change.<p>Lastly - I have a small ax to grind over people getting pets who aren't prepared to give the pets the attention they need to be happy. Pets need a lot of attention and activity - they express very clearly when they aren't getting enough if you pay attention. And you can calibrate the type of dog that might suit your lifestyle before you get one.<p>Sorry to rant over problems with fitness and pet ownership that I feel that a product like this brings up - the product itself may be totally fine and I'll probably get downvoted for saying some of this. Clearly there's somewhat of a need for a product like this.
