An interesting side-effect of Apples 8 quarter reporting of the iPhone revenue, is how - with 'delayed' revenue - it'll have the effect of exaggerating iPhone revenue in later quarters. Consider: Let's say iPhone sales for the next 4 quarters are 1m, 2m, 3m, and 4m. Apple will record the iPhone revenue during those quarters - in thousands of units here for simplicity (multiply by $499 or $599 to get the actual amount): 1st: 125 2nd: 375 (125 + 250) 3rd: 750 (125 + 250 + 375) 4th: 1250 (125 + 250 + 375 + 500) So, if the sales increase 300% over those 4 quarters, the reported revenue increases 900%. If you look over the course of the entire 8 quarters, the effect is even more dramatic: if sales go from 1m to 8m over the next 8 quarters (700%), the reported revenue increases 3500%. Obviously analysts will likely have access to actual iPhone sales figures (unless Apple includes another odd "iPhone & accessories" sales category), but it will have the effect of putting a very rosy complexion on Apple's revenue over the next 8 quarters particularly.
