This review is like comparing a truck to a race car, and complaining that the race car doesn't have enough room to hold your groceries, or comparing an apartment to a house in the suburbs. It's not that one is good and the other bad - and to provide a one star review because you prefer one to the other (or need one vs. the other) really isn't helpful.
This book provides a clear path for a user to start learning Illustrator as a drawing tool. Whether you want to use it to create artwork, text, and designs for online or interactive use, for printing, or even for things like fashion design or architecture. If you're looking for a complete course for learning essential Illustrator skills, this is the right book for you.
But if you have one or two specific questions about Illustrator, you need a reference book. More importantly, you should use the Search Inside feature on Amazon to confirm the content is covered to your satisfaction before purchasing the book.
If you are looking for a reference book because you only want to perform one specific task, and don't want to learn all the essential skills, then this book might not be the best choice. But most new users don't import files from Google Sketchup, so it isn't covered in this book. Regarding the coverage of importing images overall, this gets covered in chapter 1 (page 27) and chapter 5 has a huge section on importing and tracing images, while chapter 7 covers importing type.
If the book was not accurate, or the description misleading, I could understand this review. But thousands of people have used this book to learn Illustrator, and the content is so carefully presented to make it easy for a new user to learn the topic, that it's disappointing that a reader would simply state that it doesn't meet their specific needs, and thus must be of no value. A complete table of contents is available on the Digital Classroom dot com website and so is a sample chapter and video, and you can see some of the videos here on the Amazon site as well.
