Let's be honest here: the point of conflict is that he's black.

Woah there, apple isn't requiring Apple to put the books in the Apple store. Just inside the Kindle app, and charge 30% for purchases in that app.

The story is even more wrong than that. It's not requiring Amazon to list books in the Apple Store. Just inside the Kindle app itself.

This is not true:

Apple is now requiring third-party eBook sellers like Amazon to also make their titles available through the Apple store

Apple is NOT requiring Amazon's books to be listed in the Apple iBook Store. It's requiring the Kindle app to allow users to buy books within the Kindle app. Right now the Kindle app gives you a link to the Amazon website, where you can buy books.

It sounds like users can still go to the Amazon website to buy books, and not have to pay the 30% fee. Amazon just needs to give users the OPTION of buying books in-app and paying a 30% fee.

...where the name of the game is cramming as much information as possible into a small amount of space. Paper's dominant limiting factor was space. He says the iPhone's stocks widget could fit more information on-screen than it does. He criticizes the web browser for not using transparent buttons that would let the user see information on the web page through them.

But with dynamic displays, the game is all about minimizing the amount of retrieval time, not space. Users can tell the computer to pull up a graph for a new stock, or scroll the page downward with their finger to view the info under the buttons, or completely off-screen, with minimal effort. The biggest limiting factor is interaction. Let's keep the buttons visible, because they enable far more information than they hide.

If we sacrificed usability for screen real-estate, we'd end up with marginless documents and 4-pixel icons, which incidentally would look like windows mobile.
