OK - people seem a little interested in the idea of a book, and "Cheap PDF" seems to be popular. Personally, I'm thinking the same route because it allows be to embed hyperlinks into the document - and the book is best used when you have Visual Studio available to play with right then and there, anyway.
So then people have a few options. I'll open a poll to allow people to vote on what they think would work best for them.
