How long have you been using the iOS app store for? IMO App prices now are lower than they were when the app store first opened in iPhoneOS 2, and way lower than they were before the iPhone. I remember simple games for Palm OS costing at about $20 [0] . Nowadays that game would either be <=$5, or free to play.
