Good point. Here's a theory: laptops were running out of time and people had to opt for a new laptop or a tablet (which, at the time, had the novelty factor) and most of them decided to try a tablet. Tablets did not replace the old laptops so (some) people have since bought a new laptop. This could explain why laptop sales were down during the first stages of tablets' market penetration.
