Perhaps Glass should be compared with the Sony Walkman (which may be a bit before the time of some of those on HN). When Sony introduced the Walkman, they also invented portable headphones. Because no-one wore headphones around in public before, there was a huge stigma relating to doing so. In particular, in Japan, ear-wear was associated with deafness and hence old people.
