Definite thumbs up for Baen. They not only sell their eBooks DRM free but also give away CDs loaded with them 'and encourage people to copy them and send them to their friends', the Index page for the Claws that Catch CD is hilarious in this respect.
This is enlightened publishing since as many comments above note, there is nothing quite like holding a real book in your hands, and if you have been introduced to an author by a DRM-free cash-free eBook you are likely to buy the real thing, lots of them.....really lots of them.
Amazon need to have this business model writ large across their boardroom wall so they can understand that encouraging purchasers is most profitable than trying to control purchasers. They so nearly get the concept on their website where they suggest additional titles which you might like to try but then they let it down with the mintcake reader.
OK, for non-UK viewers this is a very poor pun on Kendal......look it up in a book as the wiki may have been tainted.
