Cortana for Android public beta now available

The Cortana digital assistant for Android, which was released as a private beta by Microsoft in July, is now available as a public beta release for US users. It will hopefully spread to other territories quicker than Cortana did on Windows Phone.
In the release, Microsoft stated:
Since we launched the closed beta, we’ve also made several improvements to the experience including the ability to set Cortana as the destination for the home button press. Now access to your personal digital assistant is just a button-press away.
You will also see a few differences between what Cortana can do today in her “native” environment (Windows) and in the app on Android. For example toggling settings, opening apps or invoking Cortana hands-free by saying “Hey Cortana” are only available on Windows for now. As with all betas, we are continually improving the experience and will incorporate feedback along the way.
New users can go to the Google Play Store and agree to the terms of the testing program before they can download the Cortana public beta.
