Query: Horrible guide, incomplete

Prior to going to Switzerland I purchased this guide thinking it would be the most recent along with the Rough Guide which was outdated. I ended up using the Rough Guide for the most part as this guide was not useful at all. It did not list a lot of the detail on the cities that I visited and was not useful at all. On top of all of that, the guide was from 2008, not 2009
