I’ve been using watchOS 4 for a few days now, and I love it. The Siri face is my preferred watch face, and my favorite feature of it is the photos & memories it shows. I thinks that’s a great feature that, I think, is what more technology should be doing today. It’s not updating me about news, sports scores, or the external world. It’s showing me memories and personal moments.
If the world around me is the external, than I (and my experiences & memories) are the internal. I would say that a large percentage of technology today is personal but focuses on the external. This is a great example of a deeply personal device focusing on the internal.
