JavaFX is Sun's new Rich Client strategy for Java. If you haven't seen it yet, check out the demos on the JavaFX home page. Unlike Adobe Flash and unlike M$ Silverlight, this technology actually works on "minority" OSes - my OpenBSD laptop with Java 1.6.0 is officially way behind the requirements, but the demos mostly work in FireFox 3 (except you can't tear off the tear-off applet, that requires Update 10). Despite significant glitches on the web site - Sun should know better - on the day of the announcement (December 4, 2008), I'm impressed.
