If the above looks like gibberish to you, it is because it sort of is.  It is referring to an add-on style menu system for canon point and shoot cameras.  The biggest selling point to me is that it enables the camera to save RAW files in the DNG format.  I think that canon should enable this feature out of the box anyhow, but that is not the point.  In the end, it turns my girlfriends already capable SD780is into a monster of a pocket camera.  Adding all kinds of functionality that was not in the original camera.  It is also non-permanantly stored on the SD card, allowing she and I to swap cards and have the camera function exactly as before.  Just awesome.
