The presentation combines data from a lot of sources, including some of the quality applications you've mentioned. I didn't break out the retention characteristics by decile, but late in the presentation there's a slide on cumulative sessions over time by decile. As you can see from it, there's a small percentage of kick-ass applications people return to disproportionately. I honestly can't tell you what's best for your business - a series of quick applications that many people will buy on impulse, use once or twice, and uninstall, or a quality application that's lovingly supported, sold at a higher price point, and gains additional users gradually through a growing reputation. Luckily, the AppStore supports both styles. Greg Yardley Co-Founder, Pinch Media
