Apple Reveals the cost of extra iCloud Storage
At $20, $40, and $100 a year, Apple offers an extra 10, 20, and 50 GB of iCloud storage.
This is less half the price that MobileMe costs. At $99 a year it gave you 20GB of storage. For a dollar more you can have 55GB of storage, or at almost one fifth the price of MobileMe, 25GB.
The first 5GB are free, and probably enough for most people since it does not include your iTunes purchases, which are stored for free.
Many other online storage solutions are cheaper per GB, but this is a big reduction for Apple. Whether it will be worth that extra money will be determined by what other services are tied to that storage, how well they will integrate with the iPad, and whether third party developers will support it in their apps.
iCloud is not yet available. It should be coming sometime this Fall.
