Query: What a waste of money!

Well, maybe I didn't do my research well enough. Maybe I didn't read all of the descriptions twice. Whatever. This book is still not worth the paper it's printed on. It simply goes over the standard apps (calendar, tasks, email) in very little detail, does not explain any of the advanced features well, does not really explain how to efficiently use the Pocket PC -- it's just specific features of specific apps... This is how you create an appointment... This is how you open an email message... That's it!!!! Anyone with a half of brain would figure that just by using the thing; for some mentally challenged there are even manuals on the net. This book has 0 added value!Yes, once again, I should've read the reviews more carefully. But I'm gullible! I was hopeful! Mr. Craig Peacock and Digital Press: cudos to you for being able to publish and sell a book like this. Don't do it again, this is a disgrace to writers and publishers who actually make an effort to sell something useful.
