Maybe I'm just unhip, but I wasn't as gaga over wearable fitness gear announced at this year's show as others were. Sure, it's nice that the Fitbit Flex fits around your wrist, but the underlying functionality hasn't changed much. Our team liked the Mio Alpha Sports Watch better, which gives runners real-time heart rate readings to make sure you're getting the most out of your workouts.

I understand the challenge in getting those who are less active off the couch, but it's going to take more than smartphone integration and social sharing. iHealth says that it's talking to insurance providers about its Smart Glucometer to potentially reduce medical visits, but I think the companies in the space need to go a step further. Why not experiment with a Progressive insurance-style incentive program that ties more activity to lower healthcare costs? That would compel me to be less of a couch potato.
