your contacts, calendars, and bookmarks between your Mac(s) and other iOS devices. You'll also be able to activate Find My Mac, which will really help if you ever (for some unholy reason) accidentally leave your $1000+ Mac somewhere or it's stolen. Once iCloud is set up on your Mac or iOS device, you'll be given a list different features waiting to be enabled. Choose the options you wish to sync across your devices. Let's take a look at what iCloud has to offer. Mail For the most part, syncing Mail is exactly what you'd think. When you initially set up iCloud, you were given a free "@me.com" account, or an "@icloud.com" account if you're reading this after iOS 6 has been released. Using the Mail option, iCloud will push email from that email account to whichever devices you've enabled. It can come in very handy, but only if you decide to actively use the free iCloud email account. Contacts, Calendars, and Reminders Enabling contacts will sync your Contacts/Address Book across all of your devices, including your Mac. Keeping your contacts in the cloud will keep them up-to-date on any connected device. For example, let's say you just added a contact on your iPad. That same information will automatically be synced with your iPhone, iPad, MacBook, etc... The same rules apply with Calendars and Reminders. Using iCloud with Reminders can be extremely helpful. Currently Reminders is not available on Mac, but will be as soon as Mountain Lion is released in
