"Home is a "family of apps" that essentially push Facebook content front and center on your Android phone.
Once the phone "wakes up," the home screen and lock screen are replaced with something called "Cover Feed." Images and posts from friends will appear as the new screen's background. Users can flip through and interact with them -- "like" an update, or post a comment -- immediately without having to open a specific Facebook app. One touch takes the user to their apps, or back to the last app they were using."
"During the event, Zuckerberg repeatedly talked about how Google's open Android system was the perfect place to build Home. It's not unusual for mobile-device makers, most notably Amazon with its Kindle Fire tablets, to tweak the system to suit their own needs.
"Anything that happens with Apple is going to happen with partnership," Zuckerberg said. "Google's Android is open so we don't have to work with them.""
Neither does Twitter, Angry Birds, Netflix - so get ready for several Home options.
