The use-cases that I see advertised are not things that I do in my day-to-day. I usually place my phone on a drawer or leave it in my backpack - I definitely don't want it on my face.
So, to me, smart glasses feel like an uncomfortable gimmick at this point. Maybe there is something amazing about them that has not yet clicked with me, but for the time being I don't see me buying one of these for the foreseeable future.
