I've avoided iOS because Objective-C scared me and I stuck to Android. I have some pending questions before I use this however.
1) How much code share can there be between Android and iOS? Is it just limited to business logic like Xamarin?
2) Can you use an Android game engine, create the game in Android and build for iOS?
3) In order to create and run iOS simulator, do you need to be on the mac and have Xcode? Any way to do it on a non-Mac machine?
4) Can you use RoboVM to create Android and iOS at the same time?
Amazing stuff!
