You may not quite realize that, but if someone wants to have access to 64 GB more music or videos then fit into the iPad, then iCloud isn't going to do it. How much fun is it accessing 64 GB of videos through 3G? When AT&T is throttling "unlimited" plans when the user exceeds 2 GB per month?
Well said. And iCloud is a huge privacy concern as well. AT&T is about to lose their shirts - people are already jumping ship. Throttling will be their death.
