I would be concerned about being dropped. They will be passed around and a lot of people with slippery fingers (or intoxicated
) might drop them. I like the iPad idea to show pictures, a lot. Depends on your budget. But I would probably put them inside a Life Proof or Otterbox case to avoid any unpleasantness of it being dropped, people feeling bad, etc., as much as having to replace them. They are very sturdy. But, like you say, people will be focusing on the pictures themselves and probably not mind handling an encased iPad.
