For years the major weakness of gmail was the really poor contacts management. Now that they have Plus users actively curating their social network into Circles, I am going to cry if that doesn't tie back to Gmail. I want to be able to email a circle. The other missing link is Google Calendar - if I have an appointment with somebody, I want to tie that it to my other info I have for that person, such as their phone number or their Plus profile. There is a ton that one could do with contacts management in Googleworld if one wanted, but I am not hopeful that Google is interested in pursuing them.
