MG Siegler is concise and right on. iPad sales this quarter was only disappointing to those who thought that Apple would sell more than 19 million units. Seriously though, think about it… Apple still sold 16 million iPads... in 3 months! The fact that this product category is only 4 years old and in total have sold over 210 million, that's quite a feat!
As a standalone business, just based on the last 12 months of revenue, the iPad would be in the top 100 companies in the Fortune 500. Think about that for a second. The iPad alone is bigger than almost all Fortune 500 companies.
