4. Working with Calendars and Reminders

One of the best—and incredibly useful—features of iCloud is its ability to keep your calendar events and reminders in the cloud, automatically synchronizing them among all your devices. Imagine you’ve just finished an appointment at the dentist, and the receptionist asks to set up your next date. Whipping out your iPhone, you enter the next appointment into the Calendar app, and in a moment, that appointment appears on the rest of your devices.

Similarly, iCloud can create synchronized reminders for things you need to do. With the iOS 5 Reminders app, you can even set a reminder to appear only when you arrive at a particular geographical location.

But probably the most useful feature of iCloud calendaring is that you can share your calendars with family, friends, and colleagues. So when your daughter adds her soccer practice to the family shared calendar, it appears on the rest of the family’s schedule as well.
