The iPad Pro is $750 for the 128GB. An iPad Air 2 128GB used to cost $700 (64GB for $600, 16GB for $500). The only reason why the math is thrown off is because they are including 32GB as the base model. That accounts for the other $50. Even when the iPhone 5S was used as the entry model after the release of the iPhone 6, the jump from 16GB to 32GB was $50. I don't know why everyone thinks the iPad Pro is automatically $100 more. It is $50 more due to the sensors needed for the Apple Pencil.
