This seems typical of Apple, if they can't get it right, don't offer it.
Rather that than the Microsoft model of offer it whether it works or not, and maybe try to fix it later. Apples rep will suffer a lot more if AirPrint is unstable and crap than if they delay it so they can "get it right."
I have no use for AirPrint, but I'm sorry for those that were looking forward to it, my boss included. His son was planning on printing school work with his iPad.
