Windows Phone 8 Development Internals book for only $10 - this week only

Just spotted this over on the Microsoft Press blog. This looks like an awesome book and you can have access to bits of it now for $10. If you wait until next week, the price goes up to $20, and it keeps going up as more of the book's available (although for your $10, you keep getting more of the book for no additional charge).

All of the details are available in the Microsoft Press post.
