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

Richard, all,

My 2 cents on this:
1. Once the code for the native libraries is open-sourced, I expect the
community to jump on it. Without source code, we are complete dependent on
what Oracle decides.
2. I hear the message that you want customers, not (only) developers asking
for JavaFX on mobile. I understand the motivations behind this.
Unfortunately, I'm not a big Oracle customer (I don't even own an Exalogic
;)), so I can't be of much help here.

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.
