I am so close to buying the 360 but was very disappointed to learn it does not have sleep tracking. I know Android Wear supports this capability so my question is....is it technically feasible and/or likely this feature will be added in the future? Aside from the battery life debate does current hardware specs support a software update if they decided to add? Really wish they had added this.....might be enough of an omission for me to wait and see what Intel/Fossil and The rumored round samsung watch has in store.
