Please, let's not go down the "AT&T is the devil" road.
You want the truth? You want to know something shocking? The loss of the unlimited data plan is the best thing to happen to the iPhone and iPad population since the day the iPhone was introduced.
Ask me why. I dare you.

I don't think AT&T are the devil or anything even close, I was referring to the OPs concerns not my own. I just don't feel the need for 3G on my iPad.
I wouldn't be surprised if the main motivation for this is just the potential impact on the network due to the unexpected extreme popularity of the iPad.
