You meant to say TSMC 20nm isn't necessarily lower power than Samsung 28nm and that's why Apple went with Samsung. Samsung 14nm is significantly lower power than both but it's reserved for Samsung's next standalone watch with built in cell call and data but with much better battery life than Apple Watch that requires being tethered to phone.
Nice, another data plan monthly expense. Glad Apple doesn't impose that.

Watch on the wrist and use your right hand to reply to the text message - the text message that you didnt miss because you felt the notification rather than missing the notification because you didnt feel the vibration of your phone in your pocket.
