The issue is clearly with the interactive needs of a student, which are different from your average reader. The existing readers are simply not optimized for student use. The study is still useful, however, because it gives a potential designer/manufacturer a list of items to hit in order to make a device optimized for student use. (Or, conversely, for a laptop or software manufacturer to target these same areas to make a better student computer, so a dedicated device is not needed.)
