If you guys are saying "swivel screen prohibits me in doing ....." or "it makes it harder to ....", those will be good reasons, but to say you don't want something because you "fear" is the reason why we aren't nearly as far as where we should have been. Trust me, I have to fight this stupid logic every minute working in corporate product development.
If decision makers at Apple think "oh man, that shiny glass will break when dropped!", then we will never have such saturation of multi-touch display in the market today, and you will still be texting with tiny keyboards and surfing the web with toggle sticks.
Furthermore, how many of you who said no to swivel screen has used one before? Just a question. I personally have and I find it useful.
