To be fair, Apple didn't promise much. The lunatic media did.
isn't "lunatic" media the result of Apple marketing?
No, it's the result of lazzyness of "journalists" who don't want to do research and come up with real content by themselves.
Since when has Apple "promised" anything about the iPad? Most/all of the hype around it was externally-generated.
I see a platform that will let Steve do a lot of "and that's not all..." in future presentations. Maybe live hd tv, video calling, augmented reality, and other wow moments in the future that wouldn't have worked on a smaller screen quite so well and need either touch, or a sturdy portable device to be practical.
