iCloud gives the users lot of new features. Some importants are:
• Twitter Single Sign-on authentication
• Automatic synchronization at all their Apple devices
• Free cloud storage of apps data
• Messaging platform
• Notification platform
• Twitter communication
Each of the feature will give us iOS developers a big advantage over other platforms. Each of them will result in better user experience and shorter development time and reduced storage cost.
Together they will be a huge plus and give the iOS devices long time advantages over Android and Windows Phone 7 apps makers.
Analysts like Horace Dediu estimates it will take years for Microsoft and Google to come up with a similar user focused cloud offering.
So, dear investor, if you ever wondered, iCloud is a lot of nails going into competing mobile eco-systems coffins.
