iDesktop would be an application to allow the creation of folders, documents, etc on your Touch or iPhone. Basically, it will be an iPod touch more like a computer. So say you made a drawing with Sketch. Instead of only opening it with Sketch or Photos, it would appear on your iPod touch "Desktop. You could drag it into a folder for it to be more organized. Later, if you wanted to open it, you would touch it, and it would automatically open in Photos. Thoughts and stuff please.
