No, it's stranger than that. People (myself included) think twice about a $5 app that will be used for a huge aggregate time, but don't hesitate at $20 for a cinema ticket to a craptastic film, or a subscription to some sort of sports channel. The app in using to write this cost me $6 and I have used it for way too many hours (and its one minor bug clipping comment length is still there damn it!)
