I'd like to propose another reason: sales tax. Simply put, the Android Market (Google Play Store, whatever) is unusable for small independent developers. With iOS, Apple acts as the merchant for all transactions and just sends you royalties. But Google foists all the responsibility for collecting tax from each individual customer directly onto the developer. For a real business with an accountant, that's fine, but if you're one or two people in a basement who just want to develop and market a game, that's a nightmare. For that reason alone, developing for iOS is so much more attractive.
