With the advent of Kindles and the like, ebooks seem to be much more viable now. I don't have one but can read ebooks on my smartphone, I'm sure many others are the same.
Nice as a "real" book is I assume that it would be easy to set up a direct system where a much higher share of my cash goes to the author, ie you.
I'd certainly be happier with that than a massive chunk going to publishers, or Walmart or whoever.
