AppsFire conducted a survey to determine how much iPhone/iPod touch owners spend on applications for their device and got interesting results.

The survey included 1,200 AppsFire users, of which there had been 15,000+ applications downloaded among them with roughly 65 applications installed on each of the devices.

Now for the money part: iPhone/iPod touch owners had purchased rough $80 worth of apps per device. The median price of the paid apps was $0.99, with the average price of paid apps was $1.56. If you consider the number of iPhone OS users, Apple is pocketing over $400 million if you want to take these stats to the bank. You can view the AppsFire presentation above.
