One small annoyance I've always had (and from searching for an answer, I know others have had) is that the nickname field in Address Book is essentially useless...it doesn't appear to be used for anything. Is this something we can expect to change in Tiger? I'd like my iChat buddy list to have people's nicknames, and my email to be sent to people's nicknames rather than their full name...i.e., "mom" instead of my mom's actual name.
