Query: Be Careful!!!!!!

I have never spent so much money on such a large volume that has so little useful information. If you are using Vista, check the other books available, this focuses on XP. I also bought 'Using Outlook 2007' and it is the same. The reading and explanations are easy to follow and understand, but I have found only a couple in each book that actually work. I do not know whether the high ratings given these books are XP users who have used limited information; but the ratings sure fooled me. I borrowed a 'Dummies' book and it has much more useful information.
