For anyone who relies on a digital calendar to keep them on track, Google Calendar Sync is a must-have application. The free download isn't fancy or even pretty--a simple log-in and options list comprises the system tray icon. However, the meat of the application is what it can do, which is flawlessly add details of Outlook calendar items to Google's Calendar, and vice versa if you so choose. At any time, you can make it unidirectional in the options, and how often the tool updates is entirely up to you.
