Is this really possible? I have the 3rd gen iPad. I have Pages and Keynote and sending my work via email works well but that's not what I want. I would like to save my work in my own USB flash drive. Plus, when I send Keynote presentations via email as a PDF document, the awesome effects can't be projected. Please if any of you can tell me if there is an adapter for that, where to find it, how much it cost and all of that, I'd be so THANKFUL... !
