If like me, the screen shot on ESRI’s Silverlight API page was a letdown, a video has surfaced that gives you some more insight into the power of this API. Silverlight really does work well, we just need more people to download the extension. I suppose it isn’t any more of a problem than the Google Earth API plugin’s problem, but I’m sure more people will have Silverlight installed that GE API with Microsoft’s push. Plus organizations can roll out the plugin overnight so there probably isn’t any reason not to go with Silverlight over Flex.
