Others disagree. "With iCloud, Apple is transforming the cloud from an almost tangible place that you visit to find your stuff, to a place that only exists in the background. It’s never seen. You never interact with it, your apps do — and you never realize it." See http://techcrunch.com/2011/06/08/apple-icloud-google-cloud/.
Apple is going after consumers who have absolutely no idea what the cloud is, and don’t care. Apple is saying they shouldn’t care.
Google seems to be aiming more for users who understand current computing paradigms and want to transition that knowledge to the future of computing, the cloud. Power users, if you will.
While the fundamentals are the same, Apple’s approach to the concept of the cloud is the opposite of their competitors. Apple’s belief is clearly that users will not and should not care how the cloud actually works.
