Really?
Your 60GB of photos has almost certainly accumulated over some time. So it's true that broadband is nothing like broad enough to solve every backup problem. But iCloud isn't about solving that legacy problem, it's about a whole different pattern where, whenever I create or acquire content, it automagically becomes available to me everywhere. Sometimes that will be instant, sometimes, fast, sometimes slow. But the real deal is that it will happen, and I don't have to think about it.
That's attractive. Maybe even compelling. But as ever, Apple isn't targeting the thin line of sophisticated technical users, it has in view the mass market who don't know and don't want to know there's such a thing as a 'file.'
