Google Calendar Sync is a neat little program that will allow you to sync your Outlook calendar with your Google Calendar.
This is handy if you need to access the same calendar from your home PC or your school laptop. If you have Outlook on your PC at home you can use Google Calendar Sync to synchronize your calendar on your work laptop to your home PC.
Google Calendar is a cool feature that it allows you to be reminded via email, or text message to your phone, for any appointment.
The downside: it only works with Windows XP/Vista and Outlook 2003/2007 - sorry MAC folks.
