Google Calendar is getting much smarter for business users
 

Google Apps users are going to start having an easier time managing their calendar. With an update rolling out this week, Google Calendar will begin automatically grabbing events that it detects in Gmail — like flights and hotel or restaurant reservations — and adding an entry for them. Those entries are supposed to stay updated, too, should there be a change in plans or a delay. Google says that basically any ticketed event should be detected.
