Much has been written about the iOS-ification of Mac OS, but what about the iOS-ification of the Web?
It began with features from iOS slowly migrating into OS X on the desktop -- like LaunchPad, gestures, reverse scrolling and sandboxing (which arrived in OS X 10.7 Lion) and it continues with Notifications, Messages, Reminders, and Notes which will arrive this summer in OS X 10.8 Mountain Lion.
It appears that Apple might be taking its iOS features to a completely new frontier -- the Web browser.
The notification (pictured above) simply reads "Default Title for English- This is a test message description" and appears to be a test of a possible future iCloud status notification and most likely an extension of Notification Center which arrived in iOS 5 and is slated to arrive on the desktop in OS X 10.8 ("Mountain Lion") in late summer 2012.
9to5Mac notes that the icon in the notification banner is the icon Apple uses to signify troubleshooting, help, and system status.
While such a feature isn't unrealistic (in fact, it feels like a natural evolution of Notification Center) it shows how far Apple's iOS features have come.
