I am one of those people who have been "corn-holed" over the last 30 years and I seriously don't care how many publishers or retail outlets I put out of business by buying electronically.
The Internet selling model is here to stay and as long as the artist or author gets their fair cut for creating the work, the model is fine by me. The fact this author is tied to his publisher is between him and the publisher and not my problem.
I've read some rubbish by established authors with ridiculous e-book prices and some fine stuff for $0.99 by authors quite happy with the e-book format, Amazon does not need to apologise to anyone IMHO in fact I'm preparing my first book for publication with them later this year, I doubt I will make much but I have a day job and the Karma value will be immense, I suspect this is the feeling of a lot of authors (yes there is a lot of shit ebooks to wade through but its worth it when you find a gem!)
If there isnt an ebook and the price is too high I go to the library or dont read it (seriously how many people would seriously read a photocopied book)
