Hover was a great innovation on the computer - to provide contextual information with a short lag (to avoid mental overload or distraction) nicely matches normal human interaction of hesitation indicating uncertainty (and thus suggesting more information is needed). Adding hover to touch would be a great innovation for touch screens and make screens more information rich without requiring more real estate. I'm not sure if it would work best as a literal hover (where a fingertip that is close but not touching is registered as a hover) or something more prosaic (a three finger touch or similar). But hover really is missing from iOS and would be valuable. And easier to use than iPhoto's help button (which has the information overload problem). I wonder how Office will handle this.
