The "EyeSight" feature has weird implications for how Apple thinks this thing should be used. I'm not really sure I love the idea of making it "easier" for someone to leave the goggles on while interacting with me.
I agree that it will always be weird to just keep the headset on during an entire conversation or to just walk around with them all the time. But if someone is doing work or watching a movie or something with these on, and just needs to turn their head to talk to you for a minute, it's a nice feature to have.
