On 6th June 2011 Apple announced their iCloud service that will completely replace MobileMe. Mail, contacts, and calendar are all free. When you sign up for iCloud, you automatically get 5GB of free storage. Your purchased music, apps, and books, as well as your Photo Stream, don’t count against your free storage. That leaves your mail, documents, Camera Roll, account information, settings, and other app data. Contacts and calendars will be updated across devices, just like they currently do, but there are several new components to iCloud.

Users can see all their App store purchase history on all devices. iBooks and progress will be synced across devices. Once daily, “a lot of your important content” will be uploaded to the cloud, making it super easy to buy a new iOS device. Just type in your Apple ID and password, and all your information will be automatically loaded up: music, apps, books, camera roll, device settings and app data.

Apple has added documents to iCloud as well. Users can edit a document in iWork on a Mac, and it gets instantly pushed to iCloud, where it can be accessed on an iPad. All data is saved and backed up in the cloud. This functionality is built in to Pages, Numbers and Keynote. File transferring seems totally automatic and effortless. Tweak an existing document in Pages on a Mac, and it immediately gets saved to iCloud and changes are immediately pushed to an iPad.
