My wife and I have: macbook, ipad 2, 2x iphone 4s We both have .mac accounts and are trying to figure out how to do the following: We want our photostreams to be pushed to all our devices We want to share a calendar but: We do not want to share reminders or contacts We are currently using one .mac account for both of us because we want photstream to be shared on all our devices. However, some problems have arisen such as "work" entry in contact list syncs to my work address and not my wife's. This makes it so that when she asks Siri to "remind me to do ___ when I get to work", Siri picks my work address. Any suggestions? Use one account for both or each use own address? Thank you all!
