One of the more surprising bits of information to me in The Extended Mind is the convincing research showing that large, high-resolution monitors make thinking a lot easier than smaller and lower-resolution monitors — to the extent that “high-resolution displays increase by more than tenfold the average speed at which basic visualization tasks are completed” (148).
I think the podcast episode gets more into mobile phones. Like so many things related to mobile learning, I think its shortcomings are magnified at the cost of appropriately considering its proper applications. Mobile learning can be crucial to learning while walking, making learning more granular, and capturing learning that happens in nature and different physical spaces. I'm not disagreeing with this point about larger monitors and when movable paper can be better, but emphasizing that this is one consideration of many other media/format considerations.
