It would be amazing if the downward-facing cameras could be used for 'typing' on a phantom keyboard. It would be weird to do so without tactile feedback, but it would make it possible to be productive anywhere, without having to bring a keyboard along. I'm sure that someone will come up with some sort of alternate text input method, given that Siri is not great at speech-to-text, and speaking out loud is terrible for privacy.
