I have a theory on ebooks.
First ebook adopters were the genres with 'controversial covers:'
JK Rowlins will bring the YA market over. That market will mature and open up every other genre to indie authors.
It amazes me how many people are getting wound up in the mechanics of how JK Rowlins is selling her ebooks. To me that misses the big picture. This brings a horde of new readers to ebooks. :) Now think of the impact once it is easier to find a Harry Potter novel in ebook form than at a bookstore...
