iPhone trumps average credit card expense per smartphone user

The data was taken from a random sampling of 275,000 Pageonce users, and includes at least 5,000 users per platform. And it could mean a whole bunch of things! Either iPhone users spend more money on average, or they have more debt on average, or the simple averaging masks extreme expenditures at the high and low end. BlackBerry and iPhone are arguably the most commonly used enterprise phones, so that might have something to do with racking up higher monthly charges.

Wait a minute.. Nevermind that iPhone users come out as the top spenders here. How can the average of 275,000 Pageonce users have an average of over $5,000+ of credit card expense each month per person?
