Google today released a series of videos about the Android platform to encourage development on it. The videos highlight two hardware prototypes - one with a keyboard and landscape screen, the other with a large touch screen and navigation pad. Google showed off the Android version of Google Maps, as well as some of how contacts, threaded messaging and calling are all integrated into the OS. Certain features like typing a name from the home screen to search contacts, a rotating carousel of applications, and even the QWERTY keyboard layout all hark back to Android’s Danger roots. Google also announced it will give $10 million in rewards to the top applications created by March.
