I looked forward to this book after meeting Chuck at a conference, where he mentioned he'd had good success getting non-programmer students to develop very useful web apps and prototypes. App Engine is a great tool for widespread use, allowing everyone with a web browser to try their hand at writing web apps... As egalitarian as it gets, these days, assuming you have internet access.
The first part lagged horribly as I crawled through the review section, and Severance trims the fat considerably (yay!) but then inserts seemingly needless low-level detail in other cases, which is a bit of a head-scratcher.
Nonetheless, its recommended to non-programmers who want to get their feet wet with cloud computing. And, it's a practical intro to Python.
