How about build their own cloud storage system rather than be Google's byotch. Apple is one of the most profitable companies on the planet, they can afford to create their own cloud storage system if they really wanted to. I'm so sick of people defending Apple no matter how cheapskate they become. I'm sure they save a lot of money using other companies' cloud storage, but that also puts them at the mercy of the other companies.
You realize that Apple *does* have their own data centres and *is* building more, right? But in the meantime, they need fast, reliable cloud storage, so it makes perfect business sense to utilize existing infrastructure. It has nothing to do with being cheap. Is that what you were actually thinking?
