Big surprise that it’s in beta, right?
I like the interface and have to admit that I’ve only been playing around with it a little bit. In the calendar settings you can import MS Outlook calendar data, which is very cool, but I’m still waiting for the web-based calendar that is going to provide a continuously syncing conduit to my Outlook calendar.
As expected, the standard Google search interface allows you to search all of your calendar events.
I like the fact that you can drag on dates and time ranges to create events much like you do in MS Outlook.
I’ve got to play around with this some more.
