Some have said more Apple watches sold in opening weekend than the entire Android watch line up in all of 2014. That many devices in the wild will make it attractive for developers and that is where I think we will start to see some real world benefits added.
That being said, I remain a skeptic about this device. I won't get this generation and maybe not the next. I am not one who sees the benefit... But it will likely be a decent category for Apple and turn profits.
