One thing I've found painfully missing, as an app developer, is any sort of analytics around the purchase flow of apps in the App Store. For example, I have no idea how many people visited my app page from their iPhone, from the web deep link, from iTunes and I don't know what % convert. As such, I can't do any A/B testing on images/text content/price, etc (actually I could but it be indirect) on the actual purchase pages.
