Lifetime content sales are predicted to 136 dollar/unit.
Majority of this content would have been bought from Amazon by other ways if they didn't have a Kindle Fire.
The Kindle fire looses money for Amazon. They can build it for around 200 dollars, but that does not include research, design, warranty and so on. Amazon will post huge losses thanks to this project. Just like the old .com days. Market share by loosing money.
Google post much lower profit then expected last...
