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 Now 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.
So long as your Android device is a Nexus or Google Play edition (that'd be the HTC One, LG G Pad 8.3, Moto G, Samsung Galaxy S4, and Sony Z Ultra) running Android 4.4, you can install the Google Now Launcher. It's not visually perfect on our HTC One Google Play Edition (there's some weird spacing), but it's nothing that can't be fixed with a few tweaks and an update. Check it out and let us know what you think.
Thanks to everybody for the tips!
