Geeky note: Last year this conference was known as MEDD (Mobile and Embedded Developer Days). When I saw that it is called M3DD this year, I thought someone was getting cute with l33t, especially given that most texting is done on mobile devices :-) Turns out, this stands for Mobile, Media and eMbedded Developer Days.
Stephen Chin, co-author of the upcoming Pro JavaFX book, attended the M3DD conference in part to do research on JavaFX Mobile for the book. Take a look at his blog post, which corroborates that the JavaFX 1.1 release due in February 2009 will include JavaFX Mobile.
Also, be sure to check out Stephen's recent interview with InfoQ that has good information about WidgetFX and JFXtras, two open source JavaFX projects.
