The new Calendar includes redesigned views for day, week, and month, as well as a new list view showing your events. As it did with MobileMe Mail, Apple has also improved performance of the Calendar application.
Sharing calendars has also become easier on MobileMe. Users can share a calendar with other MobileMe members and allow them to make changes to the shared calendars and then get notified when changes are made.
Event invitations can be sent by entering any e-mail address into an event. That person will receive an invite and can respond by clicking the link. The event auto-updates with a list of your RSVPs.
Of course, Apple made MobileMe Calendar compatible with all of its devices, so it can be viewed and edited on a Mac, iPhone, iPod Touch, and iPad. Because MobileMe uses the CalDAV standard, calendars can be edited in Microsoft Outlook on a PC with the MobileMe Control Panel for Windows installed.
MobileMe Calendar beta requires iOS 4 on the iPhone or iPod Touch, iOS 3.2 on the iPad, Mac OS X Snow Leopard version 10.6.4, and MobileMe Control Panel version 1.6 on Windows.
MobileMe Calendar beta is designed to work with Safari 5, Firefox 3.6, and Internet Explorer 8. You can request an invitation to the MobileMe Calendar beta on Apple's Web site.
