Matteo - while (for the purpose of the book) there may have been screens overlayed on photos I'm not sure I would consider that a "big error" -- because I am not in Europe it is difficult to get source material ... however, if you would like to share what you CONSIDER to be incorrect with me, via private messaging, I would really appreciate it and will make any corrections for the next release.
Considering the amount of material inside the book there are bound to be errors, I just find it interesting that you are calling them big errors--anyways, would love to get your feedback (or the feedback of anyone else) on something you think may be incorrect to make for a better product.
Thanks
