TripIt, the web-based service that automates much of your trip planning details, officially launches today. We initially covered TripIt here.
With the launch, TripIt has added a couple of improvements to the site. There's a useful calendar integration for Google, Outlook and other iCal standards, which is a very useful automation tool that goes along with TripIt's service. Sync your personal calendar with your TripIt plans, as well as the plans of your friends and coworkers, too.
