See that graphic above? It charts Apple’s revenue from the iPhone’s debut in 2007 through estimates at the end of 2010, showing that the Mac, software and even peripherals will continue to mean less to the company’s bottom line than the iPhone does.

9to5Mac is reporting that the iPhone continues to reward Apple amply, according to Bullish Cross’ Andy Zaky, who produced the graphic seen above. The graph displays a visual representation of Apple’s quarterly income revenue from the iPhone’s introduction in 2007 through the end of this year, where most everything is seen trailing off with the exception of the new reigning champion, the iPhone (as seen in red above).

How much of Apple’s business is made up from iPhone sales? By the end of the company’s fiscal 2010, Zaky expects the handset to account for 37.4 percent of Apple’s coffers, and could be as high as 40.8 percent. Not bad for a device that didn’t even exist just a few short years ago!

Among the other conclusions: The iPod continues to wane, albeit gradually, likely because the iPhone itself is cannibalizing some of those sales. The iPad also makes a strong showing in the upper right corner of the chart in bluish-grey, which should more than make up for any loss of iPod sales. iTunes also continues to be a steady earner for the company, especially since it’s so closely tied to the rest of Apple’s hardware products by this point.
