Random Tip: Detach Info
This is going to be a boon for anyone using a small screen. You can basically go to iCal's Window menu and choose Detach Info to convert the Info drawer into an Info Inspector. This then allows you to make the iCal window as big as the entire screen. Especially good for those of us with full schedules.
(Forgive the snark. i enjoy your blog immensely, but this is probably very old news to 95% of your readership.)
