Can Mono for Android be used to develop application on Android Tablets besides phones?
Yes, but you can’t use Tablet-specific APIs with Mono for Android 1.0. Consequently, you’d have to use appropriate UI constructs so that your UI will resize/reflow to make use of all available space, and you won’t be able to make use of newly added widgets/etc. In effect, the tablet UI would basically be a giant phone instead of a dedicated tablet UI. Proper support for Android 3.0 (Honeycomb) APIs will be added in a future release.
