I'm an Android user and I pay for things (?) and apps. Are you saying that I'm the only Android user who pays for apps and "things"? Or is your statement just a gratuitous cliche?
Is the average revenue per user a relevant number though? When it comes to choosing what platform to develop for, wouldn't total revenue be a more important number?
It's well understood by many startups and established companies that developing for iOS often takes priority because there's a larger group of users willing to pay more money than their android counterparts
