The existing iPad Keyboard dock supports connecting power and an external display through the 30-pin connector on the back. I'm guessing it'll work with the new HDMI connector as well, although I'm not sure.

I don't think making the iPad a trackpad for an external display would work well, however, since the iPad does not have a cursor and the GUI is not designed to be used with one (try the iPhone/iPad simulator on a Mac to see how it works). Making it work as a 1-1 mapping from the iPad to the external display is what the current HDMI connector gives you anyway.

I was suggesting the OS be updated so that a trackpad-friendly UI mode could be created. As-is, I agree, it's not useful at all.

The thrust of my wonder about a possible docking solution was towards a real, actually good, option.
