Programming differences between WPF and SIlverlight, a WHitePaper

Wintellect just posted a great 70 page white paper on codeplex about the “programming differences between WPF and Silverlight”.  

I have not dissected it yet, but from a quick scan it looks very useful.
I will be printing it and dissecting it on my flight to the next (and last) WPF for LOB Tour stop: Chicago.

Please share feedback on the paper.   Is it useful?? What is it missing?? Is it a fair assessment of the status on our continuum.
