Google Earth doesn't exist on the Daydream devices either. I've got a Lenovo Mirage Solo. I think Google Earth is too processor intensive for the mobile devices currently.
That's an interesting point. I'd be curious to know how processor intensive the app is... I've kind of always assumed the bottleneck was internet/server data delivery, from the way the image detail build-up sometimes lags, but I could be wrong.
Either way, Google Earth would be a great addition to Go.
