I spent some time looking at the IBookstore and IBookAuthor and the Twitter counter from the creator (earlier Apple Engineer) of Push Pop Press, http://pushpoppress.this year, saying Apple's product looks likes his re-branded.

I loved the products and still can't help but think about the competition between good inventions and intentions with market share (vendor bondage). This continues to raise the question of technology and privilege.
On the positive side, I've been watching custom publishing since the around nineteen ninety and also think about how we tried to get publishers working with CCCOnline to consider books as only one of their digital assets. And now the devices have added a twist once again.
Last, I intend to carefully read Apple rights to the books created with IAuthor. I'm not clear on that yet.
