Do you use Google Calendar or any other online calendar service that will let you export your calendar to the .ics format? Do you have an iPod? We've got the missing link between these two things.
iPodCALsync
iPodCALsync allows you to automatically sync your iPod with Google Calendar or any other online calendar that has .cal export functionality.
When you attach your iPod to your PC, iPodCALsync will immediately fetch your calendars and put them onto your device. No difficult configuration needed, everything is done from within a simple interface.
