I used this for keeping track of projects when I was consulting. I think it's kind of silly to track in real-time, but just checking into or out of a project is very useful on a monthly basis because you can export each project you've touched each day. If you look back at your calendar, Hours helps remind you of things you may have missed, and it makes it easy to itemize invoices.
