Query: Disappointed

First let me say the information in this book is good and informative, however, it boarders on telling people "Don't bother, it's too hard". Also, the disk that comes with it is for a financial program written specifically for photography. The downside is that it doesn't work on many operating systems, and the author doesn't have a date when it will updated. That would have been good tom know BEFORE I purchased it.
