Google just pulled a “Facebook Home”: KitKat’s primary interface is Google Search | Ars Technica
Google has adopted the Facebook Home strategy. Facebook took its normal Android app and grafted an app launcher onto it—it replaced the Android home screen with something that revolved around Facebook. The wallpaper became images and status updates from your friends, and Facebook notifications were given top billing. Everything was designed to get you to use Facebook as much as possible. With KitKat, Google is working toward a similar idea. Google took its search app and gave it wallpapers, a home screen, and an app drawer, and now it's the first thing you see when you unlock a Nexus 5.
