Android: When the Nexus 5 first came out, there were whispers that its new launcher would arrive on all devices. While you could sideload it yourself, there wasn't a simple option to download it from Google and get updates. Until now.
Today, Google officially released the Google Now Launcher to the Play Store. This launcher has new, bigger icons, a Google Now screen directly to the left of your home screen, and a cleaner app drawer. You can also say "Ok, Google" while on the home screen to trigger voice commands.
Unfortunately, the app only seems to be available for a limited number of devices right now. If you have a recent Nexus or Google Play Edition device, you're in, but everyone else has to wait. Given that Australia hasn't seen any official Google Play Edition devices, it's not a very long list. Still, that's a few more phones than were officially supported before. Hopefully, it's only a matter of time before more devices get on the list. Hit the link to see if it happens to be available for your device.
