As previously mentioned, we run Jux with Google Apps for Work. The calendar is not really what I think about when I think Google Apps but it is part of the whole service Google provides. I need colors when looking at my calendar. It helps me to understand what I was doing or will be doing at a quick glance. Was it business related, personal, church, RFL, or something else?
People typically seem to be amused when they see my calendar. I have not seen many people who keep track of things like I do. Nerd organization? How do you manage your calendar?
