After watching the intro video again, I have concluded that it doesn't make sense for there to be no horizontal keyboard. When the guy is viewing the web browser in wide aspect, there is still the menu/address bar at the top, so what would happen if he touched it while in that mode? Wouldn't a wide keyboard pop up, or would the screen do its rotaty thingie with you not rotating it and go back to tall mode, effectively being sideways as you look at it? That doesn't sound apple-like to me.
