Does an iPad last in a public exhibition? I want to use an iPad as an interactive part of an exhibition. Will it last or will it break? Does anyone have experience?
Anecdotally, I attended the Detroit Auto Show this year.  Audi had cleverly embedded iPads into the information stands next to all their cars, running their own information app. The home button was covered by the stand, so the app couldn't be exited. It made for a very impressive display.

I was there during the final weekend of the (very high traffic) two-week show. All of the iPads were functioning marvelously, and the screens were all in very good shape. That said, there was no well to tell if any had needed to be replaced. Take it as you will.
