  I certainly agree with that. There are features available on each device that change their usability and that should be factored in when deciding what should be used in the classroom. However preferences for the different functionality isn't particularly interesting from a research perspective.

The fact that reading comprehension varies between the devices is more counterintuitive and it isn't immediately clear why those differences exists. That is probably why most of the research on this topic focuses on comprehension.
