Steve Jobs introduced iCloud at today's WWDC keynote presentation, which promises to move the center of your digital life to the cloud. Essentially, all of the info you receive on your iDevices (iPhone, iPad, iPod Touches, and MacBooks) is sent to the cloud first then gets pushed down into your devices, so you're completely synced at all times. Further, iCloud "just works" with all of your apps. It's magical.
Apparently, Steve and Apple learned a lot with MobileMe, but they've written the key elements from that service (contacts, calendars, and mail) from the ground up for iCloud. If you enter a contact on your iPhone, the contact is automatically updated in iCloud and the info is pushed to the rest of your devices. You can even share calendars, which makes sharing parenting duties super easy. These three features are now free with all Apple devices.
But wait, there's more! See what else is coming with iCloud (including one interesting catch) after the break.
