Personally I don't see the video format being a huge drawback, although having the in-video quizzes in HTML5 would be fantastic for tablets. It makes it convenient to learn the content and there is always the ff/rewind buttons. You can take notes.

These remote learning classes from Standford are somewhat new and there is some experimentation taking place, I would rather not see these classes be canceled due to lack of attendance.

All-in-all a great experience, I hope more universities follow suit in this open style of teaching.
