I came accross this on Winter Olympics web site created using javaFX. While it may not be the best demonstration of the technology, JavaFX installed seamlessly when I went to that web page. The performance was good and the graphics as good as Flash. While Silverlight and Flash seem to get all the headlines, Sun/Oracle certainly seems to be steady making progress.

I came accross this article that gave 10 reasons why Flash is better than Silverlight. I agree with some of the comments there that the article is biased and Microsft has got several good things built into Silverlight. However I think it is too early for someone to drop Flash and consider developing Silverlight  applications- especially when Silverlight is installed only on fraction of the computers than Flash. I don’t know how many Silverlight developers are out there, but I doubt if it is anywhere near number of Flash developers. Nevertheless, it is being promoted by Microsoft and should be followed closely.
