I am totally opposed to iAd. I and my wife just bout iPod Touches last fall and will not upgrade to OS ad (4). Our daughter was considering the purchase of an iPad until I told her about this. In my more emotional moments I have been considering returning my iTouch to Apple. They won't give me a refund, but I won't have ads. In other moments I have been considering striking it with a hammer at the next meeting of my MUG.
I posted a very similar post to this on Apple Discussions and it was removed.
