In what world is some thing you wear around your neck less obtrusive than a smart watch alone? Know what people used to wear before the advent of phones on their wrists all day long? Hint: it rhymes with swatches. I frequently wear a single earbud (since I don't really require stereo) for upwards of 4 to 8 hours a day, often forgetting that it's even there. Look up sensory adaptation. Theoretically, everything the rabbit could do - a self-contained smartwatch could do and unlike the rabbit it wouldn't be an extra "slab" that I have to lug around in addition to my smartphone.
