did they say they sold 2 million macs in the past 12 months in the US? i thought they said they sold 2 million in the past quarter worldwide.
Official numbers are: 2.164 million computers world wide in the past quarter. 965,000 in the Americas (North + South, excluding retail) and 473,000 sales in retail. Apple doesn't give US sales, but US sales are 1.438 million, minus Canada, Mexico, Caribbean and South America, minus Apple Stores in UK and Italy.
Gartners estimates were 1,338 million US sales = 8.1% market share. That estimate would be correct if sales in the Americas outside USA and UK/Italy stores are exactly 100,000. I'd guess those sales were just a bit more, making it about 7.9% US market share. And that market share is units sold; revenue wise it is a lot more.
