Until the iOS market for apps becomes small enough that developing for it is no longer guaranteed returns I will continue to develop for iOS. The biggest issue

Until the iOS market for apps becomes small enough that developing for it is no longer guaranteed returns I will continue to develop for iOS. The biggest issue is that on the Android Market Place (Play store or whatever they are calling it these days) I still can't make as much money as on the Apple App Store for iOS. Releasing a free app with ads just doesn't work for me. So in the long run, until it becomes no longer cost effective it is going to be a long time before I switch to treating iOS as my secondary platform and Android as my primary.
