I don't understand why id should be necessary. Why isn't NSObject (or some other root class) enough?

I don't see how this directly answers the OP's question. My first thought would be that "id" can point to a non-NSObject object; it's kind of like a psuedo-base-class from which all unparented classes derive (NSObject being the most common example). But that may be an oversimplification.
