Microsoft has released the official Hotmail app in the Android Market earlier today.  This application comes with all the normal features that you would expect from a good email app. It currently supports any Android device running over Android 2.1. Microsoft does seem to be working on a tablet version of the app too, but there is no word on the release of that app.
