Apple stopped disclosing the split between notebook and desktop sales in late 2012, but during the two years before that, the former accounted for 73% of all Macs. If that same fraction is applied to the September quarter sales, Apple sold approximately 4 million laptops. The MacBook Air is Apple's bestselling notebook, so by that reckoning it sold more than 2 million, or at least twice the number of Microsoft's Surface.
It's unclear whether Microsoft's pitch to MacBook Air owners is effective enough to tempt many to switch to Windows and the Surface Pro 3. Most analysts believe Microsoft will get few MacBook Air users to change. But some think that's beside the point.
"Comparing yourself to something viewed as the premium device on the market is a good idea," said Patrick Moorhead, principal analysts of Moor Insights & Strategy, in a June interview. "You want to pick on a winner, not a loser."
