The exact same thing jumped out at me, for the opposite reason. I have unlimited data + tethering, so I can use my laptop with fast internet anywhere. That's the big breakthrough for me, not the glasses+phone combo.

Working in a park is amazing. You are still enjoying the ambience/vibe, but yeah, you're also writing a blog post or whatever. For me, that doesn't distract from the park or the productivity. They both enhance each other.

Same with a coffee shop -- this is why coffee shops have wifi passwords, because many people in there are on the internet, soaking up the ambience/vibe.
