Besides Mono and MonoDroid (and writing Java), are there any options for me? Or should I just feel foolish for refusing to returning to my Java roots? (Please refrain from Java-relat...

In android, the notification bar at the top has a shadow most of the time. However, sometimes, such as when an app has it's title-bar showing, or in some other cases (such as in the twitter app or the market) that shadow effect is gone.
