Hi again. Kind of an unusual request. I want to "mount" my iPad to a poster board for a poster session. I was thinking I would attach a back cover to the poster and then snap in the iPad. So I want one that is pretty secure. Any suggestions? I do not need to use the back again, so it's OK if I attach it pretty securely (e.g., damage after removal). Thinking Belkin, Incipio, Zum. Suggestions would help. Thanks.
