I like the month at a glance view because I can see the title of each event. Convenient for families because each person can have their own calendar, but it can be viewed with the other calendars (and they are color coded to easily identify each persons activity). When a shared calendar gets an event added everyone can receive a notification to alert to the change. The only improvement would be a better printed format.
