Microsoft seems to be experimenting more and more with Android these days, particularly Microsoft Garage. Earlier this week, they introduced Hub Keyboard.
Hub Keyboard includes quite a few innovative features and there's more coming. Features include translations, contact lookup, Office integration, and the ability to choose from a list of copied items.
The app is not without its shortcomings; however, it is clearly in beta. Obviously, these kinks will be worked out.
Here's out hands-on video with Hub Keyboard.
