We did some estimating at Pinch Media a few months back, based on our analytics data, and figured the mean (not median) revenue for a paid app was about $8K over the course of its entire lifetime. I won't claim this is anything but a rough guess. Due to the top-heavy nature of application downloads the median is certainly much lower.
