Starting off with "However, I'm not really the type of person to give accolades unless something is absolutely stellar. As such, this post will primarily be about the shortcomings of the book" I wasn't particularly surprised that there was more of a focus on negatives rather than positives.

Michael mentions three topics - the "first to market" point the reviewer makes about different versions of Magento between the book being authored and the release, some of the missing information the reviewer would've liked to see and the complexity of the example module that the reviewer complains is too hard to follow.

The initial script in the first tutorial of this series lacked some important features, such as the implementation of an effective error handling module and the ability to check the MIME type and size of the file being uploaded. In this second installment of the series, I'm going to improve the logic of the script from the first tutorial to provide it with the capacity to retrieve useful information concerning the entire file uploading process.

They look back at the previous tutorial to remind you of some of the concepts and then move on to show you how to get information about the file (like the MIME type, name and size of the uploaded file). The last page is just the full source code for the cut and pasters out there.
