Wasn't the big idea of cloud that you aren't tied to provider and can move your services anywhere? Anyway, what other big cloud providers are out there -- ones that aren't direct competitors to Apple? Amazon's AWS is out of the question, as Amazon competes directly on those hot multimedia and e-book markets with Apple. Google's stuff, too, as Google is a major competitor on mobile and multimedia markets. Microsoft doesn't seem to directly compete with Apple in the hot markets -- at least not until they squeeze some Windows Phones from Nokia.
