Community members such as Gerrit Grunwald have already demonstrated an application with a single JavaFX code base running on Windows, MacOS, Linux, Android, iOS and even Raspberry Pi.
BTW, I totally disagree with you on your comments about the similarities of the desktop UIs and some sort of unique, device-specific UI on mobiles and tablets. The truth is, the desktop OS UIs are vastly more sophisticated than phone or tablet UIs and much harder to make look good in a cross-platform way. By contrast, there is usually very little to the actual "native" look and feel of iOS or Android and skinning a JavaFX app and supporting touch/gesture interfaces etc. is comparatively much easier. I think it's fair to say that (random) iOS apps 1 & 2 will typically look more different from each other than Windows apps 1 & 2. There is no point in focusing exclusively on a desktop solution as the majority of *new* app/application development is occurring in mobile and embedded space. It's true that there are several classes of application that will *always* require a desktop OS but we must move forward and ensure that JavaFX apps achieve a separation score of zero when evaluated against my "6 Degrees of Separation" defined here: http://justmy2bits.com/2013/09/30/javafx-on-ios-and-android-six-degrees-of-separation/ To me, JavaFX is the Holy Grail we have been looking for... or at least it *will* be when the iOS and Android ports are kicking arse. And I have *every* confidence in those fine people looking after those ports that they can do just that.
