That's sort of what I was getting at, in other words, you don't really need to make a choice between silverlight and WPF because they are essentially the same thing. Maybe this is just another example in the litany of awful branding mistakes Microsoft has made around .NET? As far as books go, I'm not surprised that there are more Silverlight books than WPF. Web-centric technology books are in general more popular than desktop-centric books, particularly in the MS universe.
