Yes, why not? I don’t stand there with my wrist raised for an hour like I’d do wasting time on my phone. Apple Watch interactions are quick. A glance, a quick Siri command, a couple of taps to check off some tasks, then lower my wrist. The beauty of having my daily computer be the one on my wrist means that I live in the real world, not behind a screen. When I need the power of the internet or a digital assistant, it’s just a wrist raise away. Then I return to the world around me.
My series 0 Watch lasts me all day with 20–30% battery left. The Series 3 will be far better since it is more efficient. LTE data is also minimal. It’s not transferring videos and large images like a phone does. It mostly transmits text for messages and notifications.
