What would an iCloud service be without some way to manage files and back them up?  Not much of one.  Apple makes this super simple by having this built into their Apps such as Pages and Numbers, which released a few weeks ago had the functionality built in.  So now you can cloud your files and access them from any of your devices.

For your Apps again with the iTunes past purchases, you get your Apps past purchases.  There are apps I’ve bought and I forget about them only to be surprised I dont have to pay because I paid before.  Now I can just look at a list and see what I’m missing.  When you purchase an app, it’s available to all your other devices as well through a push feature.

iBooks now will sync across all your devices tied to your iCloud.  It will remember where you left off and sync this all to your other devices so you can resume what you were doing later even if it’s a different device.

API’s  Apple hit the nail on the head with this product and the API’s available to developers allow them to build this functionality into their apps so you can get the best features through 3rd party apps from the app store as they become available.

Backup and Restoration – OMG this is awesome.  If you purchase a new iPhone or had to replace it, and it’s part of your iCloud, just enter your account info and it’s all synced wirelessly to your new device and you can pick up where you left off.  No more picking up the pieces if you ever had to replace your iPhone or iPad, finally.

iPhones without iTunes as well no need for a PC to activate or even use your iPhone.
