Does the iPhone dock serve any purpose other than a stand for the iPhone? I've heard that there may be a difference in the "line out" electronics, anything else? I don't think there is any difference in charging or syncing is there?
You know the cable detaches from the dock. In fact, the cable doesn't even come attached to the dock out of box. I too do not use the dock - but not because I don't like it. The case I currently use makes the iPhone too thick to fit.
