Query: Ok but not that great...

Granted, there are less typos in the book than in the review given by the author himself you read above. The book is ok, a bit confusing with many missing parts. I returned it because after buying it, I would still go with the online documentation and tutorial. I haven't seen that much more material covered in the book from what I could find online already, and it deeply hurts me to see so many good trees killed by the us programmers. Note to the author: It would have been nice to show us readers some humility and rate yourself with something other than 5 stars. I gave you a 1 star to compensate for your choice... ;-)
