Digital Trends – Apple is rolling out its new, much-touted iCloud service, promising to take all the pain out of keeping computers, phones, and tablets synchronized. Unlike most existing cloud-driven services and apps â which are basically add-ons â Apple has built iCloud support right into iOS 5 (available today!), OS X 10.7 Lion, and other major Apple apps. Sign in, and iCloud transparently takes care of syncing music, video, pictures, email, calendars, contacts, and more between devices.
