Isn't this the status quo for any popular platform? The best example I can think of is video game consoles since all the sales numbers are tracked. The attach rate (average number of games sold per console) is pretty low. The Xbox 360 leads this generation of consoles with an attach rate of 7 games per console. There are nearly 1000 Xbox 360 games. So that means the average Xbox 360 owner only buys 1% of the games available for the platform. It's impossible to know how often they actually play the 7 games they buy. Of course there is a real difference between a $60 Xbox game and a 99 cent iPhone app but I feel like the model is basically the same regardless of price. The model works because there are enough users with different interests/tastes to support a big application catalog.
