If Apple is driven by profit, then the main purpose of Mac, iPod, and even iPad these days is to sell more iPhones (brand halo and integration). Isn't that crazy?

Macs were only 14% of revenue last quarter ($6.6B/46.3B). By contrast, iPhones were 52% ($14.4B). And Macs have ~28% gross margin, while iPhones have ~60%, so they add even less than 14% to the profit picture.

While any other PC manufacturer would die to have Apple's Mac business, it's mouse-nuts to Apple.
