Let's say Apple has two products.
MacBook 999$
iPod 299$
The iPod costs Apple 90$ to make. The MacBook costs them 400$ to make. (Those are figures I have in my head from iSupply).
This means in the iPods case 70% of the sale is revenue. In the MacBook case 40%.
70% of 299$ = 210$ * 10 mil = 2.1bil
40% of 999$ = 400$ * 3 mil = 1.2bil
The numbers are not the most realistic, yes. But given the fact that Apple sells iPods, iPhones, Music and Apps, among other things, next to a few computers... It is highly likely that Apples computer business doesn't lead on the revenue charts.
FWIW, here's the breakdown:
