Y'all keep fixating on HealthKit being the big tie-in to the rumored iWatch, but I maintain the bigger selling point in the long run will likely be HomeKit integration, allowing you ready and easy control for your connected house at all times, even if you aren't at your computer or already holding your phone/tablet.
I didn't even think of this! Makes sense. I think you're completely right. This will allow them to target a larger audience too! So exciting! This, if it's what happens, would make me want one even more! I'm on the edge about buying one, but this would be a great selling point for me.
