No JavaFX for iOS, Android or WP - why not?

You *definitely* qualify as a customer :-). You don't need to be a name brand, the fact that you are using JavaFX commercially is all that matters for this iOS / Android exercise.

> But I doubt there will be many end-customers asking for JavaFX on mobile. I'm active in a number of projects where the customer (and some of them are rather big, like some the biggest media companies in Belgium) require a Desktop application and a Mobile/Tablet application. If the desktop application is targeted towards millions of users, it is hard to convince the customer to do this in something else than HTML. When talking about a limited group of users, JavaFX is absolutely in the picture. 
> For the mobile, the situation is completely different. The mobile/tablet counterpart of a project is often seen as fancy, very important for marketing, should be extremely intuitive,... and most customers I am talking too prefer a native application over a mobile web application. However, at least the people I talk to don't care if it is a JavaFX app, a native iOS app, a native Android app,... As long as the application can be downloaded using the respective appstores (which implicitly indicates the app adheres to some standards), it's all good. So they won't be knocking on Oracle's door easily, I'm afraid.
> As a developer, I do care about the underlying technology. I want to write a single application and run it on every platform. Speed of development, bug fixing, maintenance, operational cost, abstraction of changes in underlying OS,... those are areas that are very important to me as a developer. As a matter of fact, it makes a HUGE difference for a developer, but a minor difference for the customer. In the end, it will be cheaper for the customer, since development cost will be lower. This will become more important in the future, I believe. But at this relative early stage of "app development" and the premature stage of "JavaFX app development", it is hard to measure the impact of development cost on the willing of customers to talk to Oracle about supporting JavaFX on mobile/tablet.
