It's a disagreement about the definition of "expensive." Apple products are more expensive than other products in the same general category. They are not more expensive than their direct competitors.

For example, while there are laptops much cheaper than the Air, the ultra books with similar specs, weight, battery life, and build quality aren't really cheaper. Another way to look at is that while Apple doesn't sell a $500 laptop, you don't get less in a $1,200 MBA than comparable $1,200 PC laptops.
