TL;DR: Smartphones with either productivity or socialization don't mix. I don't doubt it. During work, notes should be taken on paper and smartphones should be left away as a general guide. I also think the same should apply to social gatherings and meetings because the point of being with others hinges on attention. (Otherwise, it could've been done over email.) What does it say to others when someone doesn't appear to be listening or their speech slows because they're trying to read a notification?
