He's arguing that there's a market, you're saying that sales are down for a year. (Which is true after 3 years of explosive growth) For the past three quarters, Apple has sold more than 12 million iPads a quarter, or an annual rate of >48 million units. Is 48 million units a year not proof of a market?
