What's the point of the iPad / iPhone app delegates in a universal iOS app?

I've been wondering what i should use these classes for. I would think it's to set up the appropriate main view on the device. By default there's only a dealloc method added to these classes, so I figure I setup my iPhone view in the *AppDelegate_iPhone class in the -init method, yet whatever I do, I'm not able to change the background color or add a subview on the main window using this class. Perhaps I should use this class for other purposes and just use the normal AppDelegate to setup my view hierarchy for each device?

You would do stuff common to iPhone and iPad in AppDelegate and the differences in *AppDelegate_iPhone/iPad and inherit AppDelegate. If there are no differences just delete them and change the class of the delegate in both iPhone/iPad main windows to the one and only one AppDelegate.

And init will be the wrong place, IBOutlets will be nil at this place. Put your code inside applicationDidFinishLaunching.
