My experience with AppDev has thus far been very positive.  I have just started watching their series on ASP.NET using C# and look forward to seeing what is offered in an entirely different subject.

There is not much else I would seek to improve in these videos than what I mentioned above in my review (the fact that some of the videos are just a list of controls or properties that could easily be obtained in reading somewhere else).  Even the criticisms I have are not really complaints.  Who can complain about extra content?

The bottom line seems to be that, compared to the cost of hiring professional instructors to teach a topic, the AppDev training videos are a great deal for the price.  A small company (or a large one) can really do a lot with these in terms of training its employees on how to use all of these interesting new technologies.

I would easily recommend this series to anyone.
