I'm a big fan of epubbing in a lot of ways. I adore Project Gutenberg and Google Books, because I can find all sorts of wonderful hard-to-find books online for free. I love the fact that ebooks tend to be cheaper and can reach a wider audience. And, of course, there are a lot more open epub markets right now than print ones.
At the same time, when I read I want a print book. If I can get a book in print, I usually will (unlike audio stuff, which I will buy in MP3 format if at all possible). My favorite place to read is in the bathtub, and sorry, I'm just not taking the netbook in with me.
