I'll answer "No one". Most numbers I can find place Apple in first place with around 75%.

Are those international numbers? I'm just wondering, because if I would buy the cheapest nano, I'd have to pay 159€, which would be ~ 219$. That's not really competitive. The cheapest Air costs ~1,377, a 15'' Macbook Pro ~2,410.
