Exactly - the premise of the whole article is incorrect.
While the claim that the new iPad is cheaper than its predecessor aims to highlight Apple's pricing strategy, it is not a premise. Even if the iPad 2 was more expensive than the original iPad, it could still be cheap in relation to competitive offerings. It could be sold at a price allowing only for small profit margins without economies of scale. His premise is that it is.
This is a premise and it's also incorrect.
The iPad is being sold at the same price as the previous offering. They haven't adjusted their pricing strategy.
