Which apps support the vga adapter for iPad 1? iPad 2 supports full mirroring, which is great, but I have an iPad 1. How do I find out which apps support the vga adapter on iPad 1. I have failed to find a definitive answer.

For example maps, safari, google earth, photos.

I have seen references to video and itunes supporting it, but not fully.

Which apps have you used with the VGA adapter, and which features does it support?
I just tried it, Sketchbookx, Bamboo paper and pdf-notes work with iPad1 (not jailbroken) with VGA connector.
