I view a lot of these cons as pluses. In college organic chem classes we had a component of work that was online. The main benefit was that it gave instant feedback and explanations, much better than the cycle of turning in physical work to get it back 2 weeks later and never look at it again. I would rather have the better product at a higher cost than a free textbook and 1980s style grading. If you want open textbooks to succeed there also have to be open resources. It's not just less work for teachers, in many cases it's higher quality as well. On top of the digital stuff, which we used to solidify concepts, we had more involved psets which were turned in on paper. I thought it worked pretty well. So, while people on HN like to complain and say controversial things like 'the almighty dollar hath wreaked havok once more, gather hither with pitchforks', I have had no issues with this.
