I completely agree, having watched this year's Google I/O panel on smartwatch interaction design, it is very obvious that Google has put an enormous amount of thought into their watch platform. They came to a fundamentally different conclusion for what a smartwatch should do, and I really enjoy the experience. The contextual information from Google Now is incredibly useful and it feels like my watch tells me not only what time it is, but information personally tailored to my lifestyle. For example, I always go out after work on Tuesdays, and right now my watch is telling me that there is lots of traffic on the way to my favorite bar. In the morning, it tells me how long my commute will be and what the weather will be that day. I can start navigation from my watch with my voice and get every direction as I need it. I can control any music player with notification support. I don't run any interaction-heavy apps on my watch, and I can't imagine ever wanting to do so. The thought of browsing a photo library or sending my heartbeat to someone seem like features for the sake of having features but in reality are completely unnecessary.
