Perhaps you're familiar with our unique approach to publishing Charles Petzold's Programming Windows, Sixth Edition. Via this approach you're able to purchase two preview ebooks and the final ebook at one time at special pricing.
This is a quick post to tell you that we're using a similar approach for the upcoming Windows Phone 8 Development Internals, by Andrew Whitechapel and Sean McKenna. (By the way, check out the fabulous reviews for Andrew's Windows Phone 7 Development Internals.) Watch this blog: soon we'll publish details of the offer, including a pricing and publication schedule like we did for Programming Windows, Sixth Edition.
