I'm glad you like Rich's work, we think he's excellent.
On the ebook, we don't currently have the "free ebook" with print book purchase plan you're looking for. We are looking at pricing options that make more sense for customers here. The only things I can offer at this time are the PDF ebook:
The book as part of a wrox.books24x7.com subscription.
HOWEVER, before you would purchase either of those, I'd warn you that we used an experimental process for the color coded code in this book and the colored code is actually figures, not text. So even in PDF or the subscription web version, the figures aren't resizble like text would be.
Our later 4 color books (like Silverlight 1.0) improve on this and both the print code and ebooks are more readable.
