Just to throw in my two cents into this. I prefer the dead tree format myself, but I have no objection to E-Book (my wife has a Nook Color so I could use that). My major gripe right now is the pricing model. Currently a physical MMPB book sells for $7.99 for anywhere from 300 to 400+ pages. However, the E-Book cost is $5.99 for a novella that is typically only a third to half that size. I have a hard time mentally jumping that "hurdle".
