1) Books - hard copy, the original analog technology. You want to feel it, hold it, touch it, spill coffee on it. 2) E-books - What is this, the year 1648? Paper? Give me something to read on my ipad, iphone, kindle, nook, something that goes on the magic talking computer box that is always in my pocket. 3) DVD video - I want to watch it on the Tee Vee. 4) Internet video - I want to watch it on the computer box. Or a phone. Don't care where, the more places the better.
