I understand the need for competition, and I think that shaking Pearson and McGraw-Hill from their dominant positions is good.
However, I am measurably less productive in the class that requires me to use three of these than the ones that have little-to-no online interaction - devices in lecture are a distraction, automatically graded homework is a frustratingly fuzzy experience, and paying $50+ to multiple third parties to subsidize the workload heaped on my professor by the school feels exploitative all-around.
