They should have included one as a goodwill gesture.
But then again hardly gonna entice people to adopt a new standard if they have a free adapter to use old gear.
Apple is no longer the start up company and they can't just give a free adapter just to tug some heartstrings. How would they determine who didn't buy the connector because they read the small print during ordering?
It would have been good to lower the price of the adapter to a reasonable price at least for this one generation of iPhone for the people who do happen to have docks or accessories since I believe people who do have accessories with a 30-pin connector are in the minority.
