3. Advanced synchronization
Apple and Microsoft agree: It's time to say good-bye to single-user environments, where each device is a separate island from the rest of the user's computing world. Apple paved the way with iOS and iCloud, introducing a cloud-based syncing service across devices. Microsoft's Windows 8 takes the concept further, keeping not just data but application state in sync.
This shift will drastically change how people work on computers, giving applications dramatic new utility. Automatic data syncing coupled with context, such as location, available input methods, connectivity, and sensor-driven data, will give rise to truly user-centric computing, profoundly altering how IT approaches applications, security models, and other tech policies and strategies centered on user productivity.
