The whole concept of being able to mix real world (trade school) courses with heavy theory is a tricky question. We have traditional theory heavy courses in the pipeline, but realistically, it is extremely difficult to bootstrap with theoretical courses. It's been tried before and typically fails quickly. Oddly enough, you can give away theoretical classes, and you can charge $10,000 a class for them, but you can't really sell enough at our $200-$400 price point to pay for the cost of developing the class. We believe you can teach both, and should teach both, but I'm well aware that we'll always have people saying you can't or shouldn't even attempt to do so.
Oh, one note on the textbooks for the course. Of course there is an image issue when you use Oreilly and Apress texts, but honestly, for that subject there just aren't any traditional texts that come anywhere near the level needed to teach the subject. Even those three have serious holes that Dr. Ostrowski has worked with the authors to plug in this course. If you know of a better text that we somehow overlooked, please drop me a note and we'll see if we can integrate it as we create V2 of the course.
