The correlation between laptop use and verbatim note taking is incredibly useful information for it allows educators to address how students use their tools. It certainly does not suggest that laptops are "harm[ful]" or should be restricted. The "pen" is not "mightier than the keyboard."
Rather, it demonstrates the need for explicit instruction in how to most effectively take notes, either by pen or laptop. In other words, it points to the need for digital literacy instruction. Indeed, because text can be input into laptops faster than by hand, these tools actually provide a potential benefit to note-takers: the ability to take more notes.
