I would be happy with touch (or voice responsive) screens in stores telling me where to look. Surely a cheaper, maybe, more useful option. I mean all the info is there in the auto checkout, why can't there be such screens scattered throughout the store.
(PS I am quite happy to have lowebot follow me home and help me find my glasses.)
