Free e-book from Microsoft about Office 2007 and Sharepoint Services 2007

I found a new and interesting book in my mailbox prepared for Teched 2006. I quickly looked through the book, it looks quite interesting. Basically it is a book for helping the developers for creating collaborative applications and tasks with Sharepoint Services 2007 and Office 2007 System. A good reference for Sharepoint Services 2007 development and some new developments for office 2007.
