While I was away failing me third driving test Microsoft re-branded WPF/e as ‘Silverlight‘ and gave it a blingy logo. As far as Microsoft marketing goes, this is one of their better efforts.
But IMHO Silverlight is a dark horse because although a plug-in is needed to run silverlight apps, the apps themselves (some demos here) are written in plain XAML supporting the all important View Source[pdf] button.
The striking similarities between CSS and Dependency Properties never looked so conspiratorial. Who knows Microsoft may still win the Internet platform war.
