None? iOS apps are pretty far behind Android apps - the OS will only just be getting native Facebook integration next week whereas Android has had it for years. iPhone 5 has the biggest screen yet and it's still only 4 inches. Android phones have been kicking 4.3 as a de facto standard for years and the latest phones are even bigger. The main point is that iOS as an OS is behind the major player in the industry now and along with iPhone 5, will just be playing catch-up on Android for the foreseeable future.
