Apple's services revenue is growing every year. As long as their installed base keeps growing or even remains stable they can make money off of their existing customers. They aren't in the position of other phone manufacturers or computer manufacturers - with decreasing margins and only being able to make money at the point of sale.

It was reported that the average selling price of iPhones was up by $3 and would have been up by $80 if it weren't for currency fluctuations.
