How do you find the WinFX Documentation

I spent some time talking with some folks from the LH sdk team today about the quality of documentation for WinFX. What do you think? How do you find the quality of the docs in the LH SDK? What areas are good, what areas need help? If you had $100 where would you spend it? Conceptual documentation, API reference, HowTos?

 

Love to hear your feedback.
