I think the one good reason to make a phone for the budget market is app developer mind share. While developers obviously cant avoid building for iOS, the more data you see of overall users/your users coming from Android, you implicitly start building for Android first and then your iOS app "catching up". If you are a resource constrained company in India, in China, I imagine you build for Android first and then iOS. This lost mindshare would be problematic in the long term.
