Google have just released their original Android keyboard on to the Play Store, the keyboard that comes with Nexus devices.
I've always been a huge fan of the original Android keyboard that comes with the Nexus, it's amazing on the Nexus 7. Swiftkey and other keyboard replacements don't seem to do it for me. So it's great to see Google giving any Android user the ability to have a pure Android keyboard experience.
The Google Keyboard also has Gesture Typing which is very similar to Swype, where you swipe over letters quickly to form a word. It's very good at predicting the words you're trying to type and automatically provides spaces.
The keyboard is only supported on devices running Android 4.0 or above.
