(edit: I picked a terrible FAQ item to support the point that I was trying to make, which is that the phone may take longer than predicted to produce, and there's even a possibility that it'll never be produced. I think that Canonical is being very responsible by raising a lot of money as a hedge against the risks, but still, there are some risks.)
