I'm currently working on chapter 8 about the WPF manipulations API. This is a key chapter so I'm giving it some extra love and care. I'm also balancing out work and family life. It is a challenge sometimes but this stuff motivates me so I push through. I'm also motivated by the comments, feedback, and successes of my readers. If you're doing something cool with multi-touch let me know!
Since I'm closing in on half-way through the book, I posted some survey questions for readers on the Manning forums. I basically need to know how important Silverlight and Surface content is to readers so I know how much effort to put into various areas. I'm also trying to build the case for the book to be printed in color (the eBook is already in color) so the more responses the better case I can present to Manning. Please take a few minutes and answer these four questions, even if you haven't read the book yet:
