Sunrise app for Android

Sunrise is a new calendar app launching on Android today, which may very well have you ditching the native Android app. It smartly plugs into multiple services, like Facebook, Foursquare, and LinkedIn, as well as your multiple Google Calendars to provide a comprehensive look at your upcoming day, week, and month. Previous Foursquare check-ins populate days past, and birthdays pull in Facebook profile pictures. A strong web app ensures you can keep on top of things from your browser as well.

Though calendars are rarely the sexiest of apps out there, Sunrise has an extremely sharp layout. The transition from day to month view is wonderfully animated, and the way the "jump to today" button drifts towards the current date as you scroll up or down is kind of mesmerizing. Sunrise has enjoyed fair bit of popularity on iOS, and it stands to do very well on Android too. What do you guys think? Are you happy with the native calendar app on Android, or are you shopping around for something new?
