I've totally bought into the whole electronic organizer thing; I have a Palm and have been using it a lot since buying it a couple of years ago.  On Saturday, the schedule had multiple overlaps of different colors representing the activities of all four of us.

Erin had that choir thing all day.  Evan had lifeguarding class.  Mel went working at the expo center to make money for Pride.  I had a date at the pool hall with Geoff and his dad.  But we got it all done. 

Oh, and Evan's girlfriend came over to hang out.
