Google Now Launcher availability expands to Nexus and Google Play edition devices

No longer for just the Nexus 5

Attention Nexus 4, Nexus 7, Nexus 10, Google Play edition device owners: You too can now use the Google Play Launcher that was previous reserved for just the Nexus 5. That's right, no longer must you suffer with Google Now being a tap-and-hold or widget away, you can now install the Google Play Launcher and swipe right to launch right into Google Now.

It's not just easy swiping access to Google Now. That omnipresent search box is updated in the Google Now Launcher to be always listening for the phrase "Ok Google" — just say it to launch voice search. And it's a visual update with larger icons, relocated widget preferences, and other tweaks that make it easier and faster to use.
