> Really? They get data centers and bandwidth for free? They get it for significantly less than $0.15/MB. AWS S3, where Amazon likely stores eBooks, charges $0.12/GB with the first GB each month free. Even if you add the $0.03/TB to store the data and the $0.0000004 per request, and it's still more than 1000x times less than they're charging authors. Charging for 3G data might be reasonable, but charging that much for regular internet traffic is excessive.
